You have two problems: 1. your booster may be leaking enough to affect your idle 2. your brake system needs help, as in air in the system or your master cylinder has gone bad The gaskets on either side of the booster don't do anything for the brakes. The one between the master cylinder and...

Well... get us a gas chromatograph of fish oil and we'll compare! :biglaugh: Asterix

It's a bit off topic, but Wired Mag ran some WD40 past a gas chromatograph machine, and here are the results. I can't imagine putting anything on a rotor in an attempt to stop squeaking. The complete solution is between the shims, or maybe a little chamfering if that fails. My new set of...

Yup. Porterfield's R4 also squeal like an old bus and make clouds of black dust, but boy do they stop! They get much quieter over a few months, but are rarely silent. I get some good looks when they're squealing; people probably are expecting to see a bus and instead see a small-ish car. Asterix

Thanks, Zumtizzle. While I don't mind the clunk, I have some credit at Rock Auto I need to use up, so these are perfect. Soon I'll be clunkless with the best of y'all. Asterix

Interesting info, Spence. My orginial LSD from August 1987 stopped grabbing at one point, and when I drained the oil it was full of gold-colored flecks. I assumed it was friction material of some sort that came off the clutch plates. New oil with not too much friction additive didn't help the...

Yea, someone hit a tall curb from the front really hard. Good luck with cutting that bolt... Asterix

Thanks, that's what I thought. Here's a better link to Jawsgear to the proper bearing/seal kit. I don't see any clutch sets from them for our car. I'll probably start with this Jawsgear kit and get the rest from Toyota (plus a crush sleeve replacement as suggested by Poodles). Asterix

When I bought my Supra, one of the rear upper arms was stretched. As in, one side had a short necked-down section and was longer than it should've been. My best guess, based on that and other repairs, is that the car had been hit on the driver's door and shoved sideways into a curb. I bought a...

Dumbo, what's this rebuild kit from Toyota? The EPC doesn't mention one. Do you have a part number? Asterix

The MkIII has an 8" ring: http://www.supramania.com/forums/showthread.php?t=70721&highlight=differential+codes Thanks everyone for some good info. I'm about to start collecting the parts for the rebuild of my 4.3 LSD. Somebody has to have the parts we need... That link to Jawsgear doesn't...

Eh, it's not worth the effort. The rubber thing Koni supplied me has lasted a very long time. Plus, polyu in that place would have to be pretty hard to take the constant force and will let much more high-frequency vibration into the chassis. And, it's not like the location of the shock is...

Another thing to check is the tranny output bearing. Get under there, grab the front u-joint and try to move it around. Your problem sounds a bit like what I had before I fixed that. Shaftmasters makes a nice aluminum one piece drive shaft for our cars that's nicely balanced. It's even a...

I have had excellent success putting a new Toyota seatbelt in on the driver's side. The original one was starting to fray. (Maybe I should buy another pair while I still can...) Asterix

When I first got my Supra, I used Mobil 1 gear oil with the slip additive already in it. Since the Supra was my first car with an LSD, it took me a while to discover that the Mobil 1 oil had so much slip additive in it the LSD action was almost nil. When I started looking into a better...

My Secret LSD Sauce is 1 quart of 70W90NS topped off with 75W90. That way I get decent clutch action, but it's still smooth and quiet. Asterix

Shorting a big lead acid battery briefly won't hurt the battery. They're pretty tough. Shorting it long enough to discharge it completely may hurt it. I wouldn't worry about the battery. Something else let go, probably because it was supposed to, thus saving your wiring. Fuses protect the...

More than one person on my350z.com has had bushings fail after lowering their car because they didn't re-center the bushing. The one that fails is a front lower bushing and is load-bearing, so it gets much more abuse than the upper ones. (I'd post a link, but the board is down right now...)...

The stock #2 arm is way stronger and stiffer than this replacement one... Also, there must be a reason Toyota didn't use a round rod for that arm. Asterix

No pre-89 love. :( It should weigh 3.8lbs by my reckoning... Asterix
