Memento posted:ATF, just like every other fluid in your car, breaks down over time. 11 years is far longer than you should be leaving anything in your car. ATF contains all sorts of detergents, anti-oxidising agents and lubricants that will lose their ability to do their job over time. I wouldn't put a sealed bottle of ATF that was 11 years old in my car's transmission, and yours is not only that old, it's also been heated up and cooled down several hundred times, which also accelerates chemical change. I've left it at the shop for them to change out the ATF tomorrow. We'll see what they say. The flush service was $200 plus tax but I'm not sure if it's a change-out or an actual machine flush.

Unless you're running literally an F1 engine, it won't make a difference in performance (and even then it's minor). Just use normal copper plugs if you don't give a drat, platinums/iridiums if you don't wanna have to change em for 3-4 years. Multi-electrode whatever is pretty much universally a gimmick. gvibes posted:I saw a car in the parking lot with one of the five wheels lugs missing. Is that as much of a death trap as I think it is? One out of five is fine, it could make the rotors wear unevenly due to uneven stress but other than that the wheel's not gonna fall off. Rule of thumb is half minus one can usually go missing with no real issues, maybe minus 2 if it's a heavy duty truck (so 1 of 4, 2 of 5 or 6, etc). OTOH, lug nuts are cheap, so an owner not replacing them can be a sign of other issues. Fender Anarchist fucked around with this message at 04:28 on Feb 17, 2015 |

Shove down on one corner of the car with all your weight. The car should come back up, then maybe back down a little, but it should not bounce. If it bounces, that shock is bad. Repeat for the other three corners.

Wounded Unicorn posted:Tire shopping theorycraft rubberchat, please chime in with sales pitches/advice/jeering: You're not got going to enjoy the extra grip a competition tire offers without warming them up first, and warming them up is not practical or safe to do on the street. I bought the Direzza ZII when the came out 2 years ago for my Impreza WRX two years ago for Summer / Autocross, and they've been good. You still get more performance when they get some heat in them (but not too much), but they're good on the road, and Tire Rack said they performed better in the wet than the other big gun that came out at the time, the BFG Rivals (I see a mix of both at the Auto-X with some people holding out with the RS3) In terms of longevity, they have over 125 autocross runs and around 7500 miles on them and are down to 4/32s. They're directional tires so I had to have them remounted the middle of last summer because the stock suspension rolled so much that the outside edge was wearing quicker. Non-directional tires won't have this problem, so that's something to think about cost-wise. TLDR; Extreme/Max for sure, think about non-directional for tire rotations to maximize life, ZII is great but pricier now with the ZII star spec.

2007 Hyundai Accent here, about 95,000 miles. The car drove without issue last night, and then as I'm driving to work this morning I notice an odd scraping sound like the sound of something dragging against pavement, but only when I'm going slow (under 20 mph). It sounds like it's coming from the rear underneath of the car. When I got to work I checked and there isn't anything hanging down that could be making such a noise. Any idea what this could be?

It's going to get more expensive the longer it's in there. It may dislodge itself (best case), it may stay there and eat up the rotor and pad. If it hasn't done much damage yet, it could still be "turn the rotor and reinstall". How long has it been since it's had a brake job? If you're due anyway, I'd probably drive it and take it in when you can (still ASAP, of course, but a couple light drives won't cause immediate catastrophic failure).

This is more of a theory question but I've read in a few places now that MacPherson struts require an anti roll bar because it triangulates the control arms or some other obscure reason. Would somebody be able to explain in laymen's terms what the function of the rollbar on a MacPherson strut is? I'm curious because I've taken mine out of my Scirocco and actually like the handling better without it.

Asked them to "check the brakes" during an oil change because I'm getting a grinding noise during slow-speed braking. When I picked it up after hours, they wrote down that the brakes were fine at 40% on the rear. So now I have to go in and ask them to figure out the grinding noise.

The function of an anti roll bar is to counteract body roll; they're on practically every car with every suspension design (yes I know corvettes blah blah shutup) because they're a cheap and extremely effective way to firm up handling whilst having good ride comfort/stability in a straight line. Even the live-axle mustang has one. I don't think the type of suspension has any bearing on it whatsoever because every modern macpherson car I've seen has the swaybar connected with dainty, sometimes plastic links that aren't really any good for transmitting loads outside of vertical. Other suspension designs like double wishbone, simulated pivot, super strut etc all use the same principle with similar designs. Sharknose BMW's are one car I can think of where the sway bar fitted directly into the lower arm but I don't think it did anything beyond making the wheel shake annoyingly on e21's if your wheel alignment and bushes were anything other than perfect.

1500quidporsche posted:Would somebody be able to explain in laymen's terms what the function of the rollbar on a MacPherson strut is? I'm curious because I've taken mine out of my Scirocco and actually like the handling better without it. Basically, the anti roll bar connects the two wheels together. When you go over a bump, both wheels move up and down together and the bar just moves with them. When you go around a corner, the wheels move in opposite directions as the car turns, causing the bar to twist, which acts like a spring to counteract the rolling of the body. The plus side is it's like having stiffer springs when cornering and softer springs when going over bumps. The downside is if one wheel hits a bump, a too stiff anti roll bar can cause the two wheels move unexpectedly and cause the car to turn instead of going straight. It just aids what the springs are doing, doesn't have to do anything with the suspension geometry.

Many years ago my Dad bought a 1956 Thunderbird in need of a complete restoration. Now that he's retired, he's got the time to really get cracking. Some stuff has been done already - motor's built, chassis is stripped and painted, and 99% of the parts he needs are ready to go. Right now he's ready to start on getting to the "rolling chassis" point. What he's looking for is a guide on where everything bolts onto the naked frame - basically just a diagram of what holes mount what items, e.g. suspension, engine, exhaust, fuel/brake lines, electrical etc. He's very mechanically savvy (frame-off restored a 1940 Packard when he was younger), and has a lot of individual resources to draw on, so he just needs a basic guide. Any clue where such a PDF or what-have-you might exist?

So, I've got a bit of an oil leak the 5VZ-FE 4Runner, presumably behind the passenger side valve cover. It's dripping down between the oil pan and the bell-housing. I was initially pretty concerned that it was a rear main seal, but it seems to be coming from further up behind the engine block. There's also a bit forward on the passenger side lower control arm and on the transmission dipstick tube--so I think it's raining from above. It looks like the VC gaskets have been done. It's relatively clean around the valve covers and there are broken tabs on the fuel injector wire harness, suggesting someone's been in there monkeying around. The bolts themselves are notorious for backing out on their own, but the washers are fresh and bolts are all tight. It isn't enough to affect my oil level, at least at the dipstick. I'd prefer not to do a redundant job, but my suspicion is that they did not replace or use any seal packing on the rear camshaft plug. Having said that, it's possible it is still a rear main seal. Is there anything I could look for that would exclude one or the other? I feel like there is fresh oil further up the block than I would expect on a rear main seal leak, but I'm not an expert. Thoughts?

In the original MacPherson strut design, the anti-roll bar did triangulate the lower arm of the suspension. In that case, you wouldn't have a lower control arm that connects to the unit body at two place like you commonly see today (and on your Scirocco), you would have a "track control arm" that connects the knuckle with a ball joint and to the body at one point.
