4wd
I have this problem with my expedition 99. I bought it and it had a bent axle on the drivers side rear. I had it fixed. I switch to 4wd hi or low and the truck acts sluggish and makes bumping clanking noises. and when in reverse it seems as if it's going to lock the wheels. Does anyone have any answers that could help me? Mike

Everything seems OK in AWD? This may be a stretch...
When you had the axle fixed, was just the shaft replaced, or the entire axle? If the entire axle was replaced, you need to make sure the rear axle ratio matches the front. In 4WD, I believe the transfer case differential is locked and a different front/rear ratio will do nasty things to the drivetrain.

Well the guyat the shop matched up the ratio and replaced the side that whas bad on the vehicle. I read that a 4wd was supposed to clunk and stuff due to the vehicle changing gears or something along those lines. I also read that I have auto locking that engage and I have to reverse to unlock them or something. But today I will go and try it again to see what the 4wd does after driving for about ten minutes or something like that.

My 4wd (hi) is fairly quiet and performs great. I've heard others complain about noises and such. 4wd low generally causes a few more creaks and groans and shouldn't be used on dry pavement.

Ditto Iceman8984. 2wd or AWD on pavement. There are not supposed to be any noises, shudders, clunks or such when changing from 2wd to awd,or to 4Hi if on a slippery surface. There will be a chunk or clunk when shifting to 4wLo and back again.
If you had the axle replaced and it was Limited slip, it will make destructive noises if enough friction modifier was not put in the diff as the oil was changed. And, it will destruct if you continue to drive it making noises and vibrations. Usually a chattering sound when turning right from a stop.
