Learn from my mistake: clunking diagnosis

[TOKKA]

I think we're on different pages of the same book Joe, I was talking about through bolting the mount itself, to make it solid (and to keep from $pending money on a new one)...
Here is what I meant...

Great Pics, great point, and great info from all, but I don't really see what's wrong with the XMSN mount pictured. I see the bolt through it... BTW turned out that my left side bolt was in fact loose, however the "clunk/tap" did not go away. In fact, I can reproduce it with the drivetrain in Hi or Lo, forward or reverse, as long as I'm increasing acceleration between 25-50 mph. I'm very afraid to drive far! I have never had a jet, helicopter, or weapon system stump me for so long.

25-50 mph in reverse ... that's some hard core wheelin bud.

IMHO, keep the diagnosis simple and work towards the harder stuff. Check CV boots for tears. Check bushings for cracks. Grease anything with a Zerk. Check that all bolts are tight. Check heat shields around exhaust. If you have skid plates, make sure they clear all exhaust and suspension components. Check tire balance. Check brakes for any trapped stones.

Service Tranny. Replace fluids in both pumpkins & TX case.

Even if it's none of those things: 1. should do it every few years anyway & 2. you may locate the real problem at the same time.
