Clunk noise when putting truck in reverse
So just recently my truck has been clunking when putting it in reverse. I checked the U joints and they seem fine. The noise seems to be coming from the yoke that goes into the transfer case. There is no vibrations at hwy speeds or clunk when in drive or driving. If I grease it will this stop?

when you checked the u-joints was there any up and down play in the slip yoke going into the t-case? sometimes the bushing in the t-case wears and causes the noise. Mine made a similar noise. But, mine happened going into reverse and drive. i greased the crap out of the inside and put a thin coating on the outside and the noise stopped.

Usually the "clunk" is caused by excessive movement off the parts connecting the transmission to the rear axles, it could be in the tranny, the t-case, the u-joints or the diff. It is usually one, or more of the u-joints, or the bearings at the yokes.
Some "clunk" is normal, there should be some play in the pieces.
I usually turn (twist) the driveshaft back and forth and try to see what mores more than normal. Try twisting and pushing up and down, sideways as well, at the front of the driveshaft and at the rear.Ray

I think I figured it out. There is movement up and down in the yolk going into the transfer case.
