Nope, no chance of the exhaust...or anything else that might be hot back th=
ere. The heat looked like it came from the diff cover out to the poly bush.=
The bush was melted the most on the back edge where the cover had the bigg=
est mass next to the bushing.
And this is with a Detroit locker, no heat building clutches inside!

Wow! Melted poly mounts! Never seen that before! Sure it's not the exhaust =
systems proximity to the differential casing that's adding to the equation?

If not, who has installed a pump and cooler back there? What did you use fo=

Usually in hot water myself...this time oil!
