Has anyone experienced problems with the rear end leaking where the flange connects to the differential housing? I have the car in twice and both times it was fixed.....for about three days and then the leaking resumed.
This sound weird, as I have never heard that 1 bolt will create a leakage issue. The differential is connected to the trans with 2 bolts, and 3 studs with nuts.
There is a large o ring, and 2 seals between the 2 assemblies.
I find that there may be some thing else here.
Let us know if the condition reappears, best to ya, c4c5
It is possible, but I dont believe so, as brake fluid would not be that slick.
One thing, as you look underneath, is the fluid leaking from the top, down the housing, or is it directly from the hole??
If it is from the whole, I would suspect differential fluid, as the Dexron 3 in the transmission would be red.
Take care, and please keep us posted, c4c5
Hi there yes there have been several leaks at the rear diff. No it is not because of missing locktite.The most common are the side cover o'rings on the drivers side.I have had several cars from other dealers that couldn't repair a rear end leak.It is not the the o'ring between the trans and the diff.It will look like it, but it is not there is 2 seals in the trans rear housing and a weep hole on the bottom of the diff. The seals fail and fluid leaks between the trans and rear diff.
i have an 03 i had it in 4 times for the rear end leaking in less than 1000 miles they finally replaced the whole rear end. have not had a leak since, they said it was defect in the casing from the factory.
I was walking back behind the Vette yesterday while it was parked in the garage and I notice the strong odor of the Read Diff oil. Is this normal or do you guys think I have a leak. There is nothing on the floor, drip wise.
Yep....It's the O-ring. Mine just started leaking and I wanted to know for sure what it is before going to the $tealer regardless of it being under warranty. So I took it to an EX GM-Mechanic who works on Vettes and that's exactly what he said. He mentioned that it is a common problem. So mine is going in next week fr the same thing.
I have 4000 miles on mine and just noticed a drop on the floor. Went into the Sherlock Holmes mode and discovered the right axle seal is leaking from the diff. It's my suspicion that replacing the seal alone will not cure the problem. I would imagine the seal housing should be replaced as well because of the sloppy tolerances that develop in the housing after a few burnouts, etc.
