Seasons Greetings !
I've owned my 1996 2 door Tahoe LT 4x4 practically since new , it was still well under the 36,000 mile limited factory warranty when I got it . From the very start it had the driveline clunk problem which the dealer seemingly made go away by pulling the driveshaft and greasing the splines . This "fix" never lasted very long and it had to be done multiple times ... up untill the 36,000 mile point and then I was on my own . Not many miles later somewhere in the 60's the sunshell in the trans let go taking out the entire unit (metal throughout) so I put in a HD towing 4L60-E with a new torque converter and life was good again . Shifts were vastly superior to stock unit , ect. But it still clunked. Fast forward to a month ago when I was pulling away from a traffic light on a road that was being repaved , it was only partially done so one side of the Tahoe was on a raised lane of new ashpalt and the other side was riding lower on the old roadbed height. There was a bang , some grinding and totall loss of all forward movement. The only way to get it going was to manually shift it into 1st and then it went "into gear" . Once moving it would shift on it's own if the shifter was put in drive. But from a dead stop it acted like it was in nuetral. Reverse worked fine and all gears were available. It just wouldn't take of from a stop unless dropped into 1st. Diagnosis :
Forward Sprag busted in the Trans ... so the replacement transmission made it to just over 100,000 miles before calling it quits . I replaced the one piece bellhousing 4L60-E with a newer generation removable bell type 4L65-e?) which swapped in fine . Thinking all is well again I went to test drive , backed down the driveway , put it in Drive and ... Bang ! GRRRind, grind. Clunk. VERY loud noises. Dropped the transfercase and split the case to find ... major gear tooth damage and fractures. Found a replacement, internalls checked out good so in it goes . Got the truck all buttoned-up and confidently go for a test drive ... BANG ! BANG ! Clunking grinding noise all over again !! Unbelievable . What now ? Turns out the rear end had taken out the entire drive line from busted spider gears . Now I need a complete rear axel assembly to swap in and don't know what I can safely pull from which donor vehicles or years . It's a 2 door 4x4 with 3.42 (GU6) can anyone point me to a suitable donor truck please ?!
Thanks VERY much and Happy Holidays !
