The clunk thing

[MoonRaker]

Ok, ive read most of the clunk catagorys but I dont think ive found any answers. I was having a clunking problem before when id make sharp turns. I shifted the transfer case to 4 low and pulled the E brake as hard as posible. I had someone get in my VX and told him to shift from foward to reverse. Holy crap, the front diff moved about 3 to 4 inches on the mounts, thats not rite at all. I pulled the front diff to check the mounts and they were fine, a buddy of mine told me to make some urathane shims because the mounts might be week from age, abuse and that fixed the problem. It worked well till about a month ago. Now when I lay on the brakes to make a stop then let off the brakes I feel and hear a major clunk and its not gear lash. It sounds like a major shift of a componant. I cant get it to act up on a lift either and I checked that all the bolts were tight. Im about to rebuild my transfer case bacause of leaking seals. Anyone think it could be that the chain in the transfercase has been over stretched or is there any other ideas. The truck runs strait and feels very tight and smooth considering the abuse ive put it through. It used to start shaking a little at 75 but after the shims were inplace it drives smooth as silk to 100 plus. I wish I would have done that before I drove crosscountry. Ive noticed alot of the same style mounts on alot of the moving suspension parts and im thinking of shimming them all.

my VX has always done that clunk after very hard braking, just figured it was normal. i prepare for it now, when i come to a hard stop i just shift to neutral for a second to relieve the tension

My VX would clunk if I didn't come to a complete stop and then hit the gas. The transmission had a slight leak and it was slipping. Maybe that's what is going on?

Na, tranny is tits. Ive checked the fluid when I changed, no band crap.

Im pretty sure its not normal, atleast on mine. Im woundering if it has to do with the rubber mounts in the A arms. Maybe you load them under hard braking and when you release them they become unsprung causing the clunk. Another thought is like I said before about the transfercase chain having slack. There does seem to be alot of backlash in the drive shaft entering the transfercase. If the rebuild for the transfer case costs 1100 in part, I wounder how much it would cost to put fresh gears, bearings and seals in the front and rear diff, couldnt be that bad. Im trying to keep this truck alive for atleast another 100,000 miles if not more.

not sure what could be cuasing it but its a similar feeling to when i start the vx and put it into drive while the e-brake is still pulled. the vx doesnt actually move but it feels like its raising

That's axel wrap & it's normal.

i was going to ask about the clunk too. when im in low and shifting between drive and reverse there is a cluck and jerk. i twisted the drive shaft by hand and there is about a quarter inch of play, so i assume the clunk is the drive shaft twisting free before catching and that low range amplifies the jerk by applying more force( torque ). i was thinking worn u joints, but could you explain axle wrap as this may be the problem.
