[QUOTE="69fb, post: 6701884, member: 33763"] I have a 99 cobra that has some OT modifications. It has a squeal in the rearend that sounded like it was coming from the rear diff. The squeal develops only after the car has been driven for about 10 miles or so. (the rear starts getting up to operating temp) There is no squeal when it's cold...in the first 10 miles. This squeal is weird...at anything under 20 mph it goes away...but anything above roughly 20-25mph and it can be heard. It's loud enough that it's audible outside of the car when driving next to barriers or buildings. It sounds like a brg is on it's way out...but this car also has a Torsen T2...and I've read they tend to wear out prematurely...so I suppose it could be that as well. I pulled the rear diff yesterday and took the cover off...nothing obvoius and there was not any metal seen in the fluid. WHile it's apart i'm going to replace all the brgs and and seals...and probably remove the T2 and replace it with a spare t-loc I just picked up. (unless I see a brg was definately the culprit of the noise, then i'll keep the T2) I plan on using all OEM brgs and seals for the rear diff..but while disassembling yesterday, I noticed the spherical brgs in the knuckles (top and bottom) had the boots torn. The brgs themsleves felt tight. 1.) Can I buy just new boots for the knuckle sph. brgs? 2.) If I have to buy new brgs and boots for the knuckles, should I replace with OEM or is there a good quality aftermarket brg available for rated OT use? [/QUOTE]
