I ran 35" tires on my f150 with a 8.8 rear end and it had 290k on it when i got rid of it no problems so id say no.. anything that will fit on a mustang is not going to screw up the bearings in your rear-end unless you dont have enough oil in it..

No, the tires won't wear out the rear end bearings. That doesn't mean the bearings aren't bad though. In fact, since everything is apart already, you should change them.

yea we changed them... i didnt think it tires would harm it..he said there was an offset or to much of an load on them but its changed should be good...
thanks

No... I see this at work all the time, old mechanic tales..


My favorite one is the you need X amount of horsepower to push shorter gears.. Facepalm is my typical reaction to this..

It's definitely not related to the tire size.

If I remember right there was one year (2001, 2002, 2003) where a few people were running into failed rear end bearings and had them fixed under warranty.

good to hear ..any chance i will bust an axle

Are you running drag radials or slicks? And I'm assuming they are stock axles.

yes stock axles...and no just 315 reg street tire

On street tires your axles should be fine.. but the 28 spline stock axles can break on a good launch with DR's or slicks

I just had my T-Lok rebuilt at a shop ($375). The tech said alot of the bearings in Ford 8.8 diffs go bad. I was told that mine were probably shot based just on my mileage (49,000 miles). He did say, however, that both of my axles are pitted and the axles and axle bearings will need to be replaced shortly. I was told they kind of make a humming sound when they are on their way out (like a wheel bearing). It's really disappointing to have so much rear-end trouble on a car with not alot of miles on it. On top of that, I run stock sized tires and they are not DRs or slicks, and I don't smoke the tires or abuse the car.

I hear all the time that Ford rear ends (in general) are pretty tough. Maybe I just have bad luck ...

The pinion bearings on my 97 GT went bad at around 150k miles. I can't complain too much, because it lasted so long.

The 7.5 in my 88 seems to just keep ticking. It is suppose to be pretty weak, but the poor little one legger regularly goes 1.7 60' times.

Ive been getting a random grindingish type of noise lately from my rear drivers side. Just had my brother install my new shocks today and he said my barrings were bad .... so pissed. I guess Labors going to be a kick in the nuts

Axles do not need to be replaced unless you want to spend lots of money. You can buy repair bearings which ride at a slightly different place on the axle.

Are you sure? The guy at the transmission shop seemed pretty sure of himself.
