A buddy of mine's 01 cobra began to squeak last night and noise is from the rear. There are some drops of oil on the catback and a little on the gas tank. Looked around the net and found that slowly leaking diff is very common on 99&01 cobras. Squeaking is most noticeable in 3rd & 4th gear at around 2-2500 rpms. Was only in his car for several minutes but I myself felt car wasn't accelerating properly. Anyone ever had this problem before with the 99&01 IRS

Most likely the diff is dry (out of oil) and bearings are seizing up.

I wouldn't drive it, if it
Is a pinion bearing and it does decide to lock
Up and spin the race you may be looking for another center housing

I recommend pulling the IRS pumpkin out of the car to fix the leak and then upgrading it with a Ford racing cover, eaton tru Trac, all new polyurethane bushings, new seals.
