I will be installing my 4.10's sometime soon and my mechanic told me there was a problem with the diff. going out. My car has 55K miles on it. i was wondering if this is a common problem or has happened to many people. If so, i figured i would rebuild it as long as I was installing gears. Thanks

 

anyone??

 

mustangs are not popular for differential failure, they are just as prone to it as any other car manufacturer...now plastic intake, yes =p

 

ok well i noticed that there was a TSB on it so i was wondering if i was common or not .

 

its not common, but there have been a few people here including myself that have had a bearing go out. It wouldn't hurt to have them put a complete bearing kit in at the time of the gear install. its only about another 100 bucks

 

A bearing kit should be a must when installing gears.... It is very cheap insurance compared to the rear end going out.

 

no its true the clutchs in the diff pit after like 10000 miles on some peopls rides... 45 bucks for the clutchs DO IT

 

Yea i have an auto, so dont have to worry about clutch, and i ordered a bearing kit along with my gears. now i jaust got to get them installed. i hope they are as fun as everybody says.
