Rearend rebuild

[Skremr]

I just had some great work done by Gearheads. I've got an '03 Cobra making about 550 rwhp and have had a lot of rearend trouble with the car for about three years.

I've had three rearends, one of which was a Detroit Trutrac. The factory diff was fine until it lost diff fluid and Ford replaced it under warranty. The dealer did a crappy job and the new rear was noisy from the get-go. Last summer I had a Detroit Trutrac put in but was never satisfied with it as it was noisy in cold weather.

Gearheads put in a new ring and pinion along with a complete new factory original differential setup and it is quiet as a mouse.

I've owned a 99 Cobra and now the 03 Cobra, so I've had my share of all the IRS symtoms including the "vibe", the "clunk" and I had forgotten how great these IRS setups can be. The "clunk" is gone and I thought that was impossible to get rid of.

Thanks Chris and Travis

I would guess its the rear end if its doing it while shifting... does it only do it in lower gears? When I had Irs mine only did it going into 2nd and 3rd, sometimes if I rammed it hard going into 4th also
