Drive shaft troubles
OK so there is a front drive shaft. on the left side is the transfer case? that shoots the rear shaft out and the front shaft to the right wheel. It makes this wierd thunking noise almost like a stick on a bike tire. But here is the wierd part it only does it while the truck is in 2wd. When it is in 4wd you would never notice. Does anyone have a clue to what is making this noise and how to fix it?
thanks in advance
