McGard makes a two piece spline lug that's been fantastic. They have shoulders to stop the socket from marring wheels as well as a floating taper face to not gall the paint on the seats of the wheels.

Get ready to pay, though. Their standard lugs have been good too if that seems wild to pay for lug nuts. I have them on my Rays.

Why would they not be? It's a half-ton through one-ton commercial truck platform. Rear wheel drive is objectively superior to front wheel drive for towing or carrying heavy loads.

Smaller vans are generally FWD, but the Transit is the largest van Ford makes. It competes with the Sprinter (also RWD) and the Ram ProMaster (FWD). Guess which one you almost never see compared to the other two...

Exactly.

Front wheel drive has plenty of advantages related to packaging and drivetrain efficiency, at least for now while we still need to turn a series of explosions in to rotation and transmit that to the wheels, but it is always a compromise from a performance/capability standpoint.

No one should ever "want" front wheel drive. It's just something you end up with on certain classes of vehicles because it's cheaper and the downsides don't matter to most users.

Fortunately EVs eliminate most of the packaging advantages so most dedicated EV platforms are RWD or rear-biased AWD. As someone who loves his FWD hot hatch, good riddance.

You can buy them rear or front drive.

The boss upgraded from the old rear drive transit to the pictured model from drive and it is absolutely a dream to drive.

I thought I was gonna hate it going from manual to auto, but it is a phenominal engine and the auto box is really good in it too.

Bar that picture, the fixed absolutely everything that was wrong with the old one but introduced one really wired bug.

If you pull the handbrake when it is in drive it pops a warning on the dash and the warning chime goes off like your stealing the car, but if you leave one of the doors open and go to take off, no chime, just a little bit going on the dash saying door open.

The previous generation full-size Transit was offered in both FWD and RWD variants. The current generation introduced a midsize FWD variant called Transit Custom that doesn't make it to the US and the full size model went back to RWD/4WD exclusive.

Ford Body Builder appears to only offer Transits RWD or AWD depending on the chassis type and model in the US.
https://fordbbas.com/publications

Digging through their UK site, there is at least a cutaway model that are FWD and some other models as well.
https://www.ford.co.uk/shop/specialist-sales/transit-conversions/ford-conversions/skeletal-chassis-cab

EDIT: Having never seen one, I'm guessing FWD Transits still use longitudinal mounted engines and are basically the AWD model without the rear diff and prop shaft and with a locked transfer case? The re-engineering to have it have a transverse mounted engine would be absurd though I wouldn't put it past Ford (or really any manufacturer) to have that capability in mind if there is a feasibility and business case for it.

large vans with longitudinal engines always have loads of room around the engine. So if you need to have an AWD variant anyway how much additional engineering at the design stage would really be needed for a transverse FWD variant?

If that's the case, then why do they appear to be tied into the steering control mechanism?

If I understand how this works, then the mechanism at the top of the diagram controls the steering by applying rotational torque to the steering differentials (Lenkdifferential) near the left and right output shafts; the transmission drives the ring gear, the steering mechanism drives the sun gear, and the output is connected to the planet gear carrier. When the ring gear and sun gear are rotating at the same speed and direction, then the planet gear carrier will also rotate at the same speed. Speeding up the sun gear will in turn speed up the planet gear carrier. Slowing down the sun gear will in turn slow down the planet gear carrier while rotating the sun gear in the opposite direction will further slow down the carrier to the point that it can be completely stopped when the sun and ring gear are rotating at the same speed in the opposite direction. If I had to guess as to how it works, the Nullwelle (zero wave?) connects the two steering differentials together but are geared to rotate in opposite directions. The Nullwelle is stationary when you want the left and right output shafts to be rotating at the same speed to travel straight. Rotating the Nullwelle so that left sun gear spins faster and the right sun gear spins slower will result in a right turn and vise versa. Having the Nullwelle spin faster will result in a sharper turn.

The steering mechanism (Lenkhebel) appears to control the flow direction and flow rate of oil going from the control pump (Rengelpumpe) to the "oil engine" (Ölmotor) which in turn drives the Nullwelle. The control pump appears to be driven by the fan drive (Lüfterantreib) which suggests that it is an additional power input into the transmission. Maybe it's called that because it's part of the engine's cooling fan and accessory serpentine belt or at least maybe that's the etymology. The fact that the transmission input coupling is on the opposite side suggests that physically isn't the case. Looking at pictures of an actual HSWL 354 have me more confused because they don't precisely look like the diagram. Even so, it appears the actual units appear to have cooling fans mounts on top of the transmission that I guess provides cooling air to the engine compartment and radiators. If I had to take a guess, I think this diagram is not a single-plane section view and is in fact a two-plane right-angle section view with the transition between the two sections occurring along the centerline of the output shafts. The bottom half of the diagram is a section view looking at the top of the transmission and the top half is a section view looking at the front of the transmission. That means that the fan drive are in fact referring to the aforementioned cooling fans. As for how power gets to the fan drive, I think the answer is the green gears that have arrows pointing at them as I think this is how the green components in the upper and lower half of the diagram are physically connected.

I also have no idea what the exact purpose hydrodynamic steering couplings (Hydrodynamische Lenkkupplungen), which also appears to be driven by the fan drive, are but the layout suggests it's a pair of hydraulic fluid couplings that are oppositely geared to the Nullwelle. Assuming the fan drive is in some way coupled to the engine, perhaps it's a mechanical regulator that limits how sharply you can turn depending on how fast you are going. The faster the fan drive is spinning, the slower the Nullwelle can rotate since the hydrodynamic steering couplings will be applying more opposing forces onto the Nullwelle.

As for the transmission itself, it appears to a typical-ish slushbox automatic.

This is all guess work, mind you, but with my background in mechanical engineering and experience with CAD touching I have some idea what's going on and why the diagram may be drawn the way it is. Sorry if my explanation is all over the place but I was slowly figuring things out as I was writing this post.

Good spot on the confusing steering assembly.

The brown shaft (Nullwelle) is what is actually used to steer the tank, it forces one side of the differential to speed faster or slower than the other side, creating a speed difference between the tracks which turns the tank. This is called regenerative steering because you don't apply any brakes and turn without dumping speed (apart from track friction and losses)

Usually the Nullwelle is turned by the hydrostatic motor, powered by the hydrostatic pump with variable stroke, of which the stroke adjustment is coupled to the steering wheel.

This allows very precise speed adjustment between the chains.

The hydrodynamic clutch does the same thing with much higher speed of the Nullwelle, this is done for neutral steering (turning the stationary tank on the spot very fast). The transmission has a special gear for that (W - the second neutral Position). Neutral steering via the hydrostat should be avoided because it puts a too high load on the relatively small hydrostatic motor.

The historic alternative is turning a tank with an open differential by applying brakes to one output shaft. This is done by the classic big rear end levers that can be seen in indiana jones and the last crusade. The levers usually have a ratchet lock like a handbrake and a the driver has a cheat sheet with brake position, gear and engine speed to achieve a certain turn radius.

The FWD models have different engine and transmission options than the R/AWD models so I'm pretty sure it is in fact transverse.

Trying to search for any information about front wheel drive Transits from the US is hard though because the search engines prioritize US content which means all kinds of useless articles about Connects. It doesn't look like they were particularly popular, for obvious reasons.

Had to trawl through eBay since that's where Ford UK sent me when looking for parts but I think I found the transmission for a FWD Transit and it does look like it's transverse mounted.


https://www.ebay.co.uk/itm/Ford-Tra...+V363+FCD%2CFDD

As I said earlier, I'm not surprised Ford made a transverse setup for FWD. That said, it actually looks like the transaxle does make for a cleaner looking package as opposed to lopping off the back end of an AWD model. On the other hand, the logistics for maintaining different parts for FWD models and R/AWD models must be inconvenient at the very least.

EDIT: Turns out a Transit Custom isn't actually a Transit, I think. At least not the same one in the US. A Transit Custom is slightly smaller and is FWD only from the looks of it. In any case, FWD Transit (not Custom) still appears to be transverse FWD.

Is that a challenge?
The 'default' Transit in Europe (swb, regular roof panel van) is FWD and always has been. Once you start optioning stuff they will happily sell you a RWD or 4WD model, but the basic van is FWD. I'm actually impressed they crammed a longitudinal engine in there without half the engine vanishing under the cowl.

I understand the benefits of RWD in respect to hauling heavy loads or towing, but the Transit pictured earlier looked to be set up as a mini-bus. I can't see how that vehicle full of people would be so heavy that a FWD drivetrain cannot perform adequately; and I imagine that the lack of a driveshaft / rear axle would result in a lower floor, which would make the vehicle more practical. It also does not have a visible tow bar.

All information I have says quite the opposite, that the FWD full-size Transit has only been a thing since 2000 and it seems to be something you have to go out of your way to even find on the latest models.

By default, the Transit van in the US (not the Transit Connect) is RWD - it replaced the Econoline lineup, though the Econoline was still built for cutaway chassis stuff until VERY recently. Only the Connect (which is sold as the Tourneo elsewhere, I think? and loosely based on the Focus) is FWD by default here - and also by default (not sure if this still happens, but it used to be the norm) the rear seats and windows get removed after importing them, to avoid some stupid tax laws in the US.

Looking at Ford's US website, you can only get the Transit in RWD and AWD, and only with a 3.5 V6 (you can choose NA or turbo), 10 speed automatic only. You can basically choose from GVWR, gear ratios, roof height, length, and not a whole lot else, as far as the the main stuff goes. Whole lot of other options that mainly apply to fleet usage. They even charge extra for putting windows in them (aside from the windshield and front doors).

Speaking of vans, there is a newer type panel van (sprinter/transit or whatever the gently caress) around here with a 70s style custom paint job on the sides and the (probably) fake little round window in the upper back. I just started noticing it recently, I'll try and get a picture of it.

The reason why Ford doesn't offer the Transit in FWD is likely because there wasn't a big enough business case to justify the cost to do crash, emission, fuel economy, and other testing on the FWD models to Federalize it and able to offer it in the US. Which I think is a valid decision because the majority of Transits are being used to haul equipment or cargo where RWD is better suited and passenger van Transits are almost always used in a commercial setting where the benefits of FWD wouldn't be considered necessary.

There's also the additional logistical overhead of maintaining FWD specific parts since FWD Transits are transverse FWD. I mean yes the rest of the world is getting by with that but I'm sure Ford preferred to not have to deal with it when they launched the Transit in the US in 2013 and tool up for a new platform.
