on the same old girl (91 Z71), what is normal to expect on the front diff?? I shift into 4x4 religiously to keep things moving....the 4x4 light no longer comes on (understand its simply a switch?) after a bit of a delay (not much) 4x4 does come in and work normally.
I've always had a bit of transfer case hum when in 4x4 at higher speeds, and a trans shop said not to write home about it till it explodes.
However...the other day at the dump I shifted into 4x4 at coming to the base of a hill...I guess it decided to wait till I was climbing the hill to go into 4x4 and I got a "clunk". no big deal, but what was that????
Also, its prolly about time for a front diff engagement solenoid. somebody listed the gm part numbers to do the electric motor upgrade (the motor itself and a harness to retrofit). can someone re-iterate?
any thoughts on what other peoples front diffs are doing on early 90's chevy's? I just want to know mines not doing anything abnormal (and about to explode).
