Hi all, COuld use advice, again. 2002 yuk 4x4 with 191k miles. last month had major work done as I plan on keeping this rig for awhile. Front diff rebuilt, including ring and pinion (mainly was for carrier bearing but ring and pinion had wear suggesting preload, backlash etc was way off.) ALso had oil pickup tube oring replaced, front engine and crankshaft seal (leaking oil), oil pump replaced. transfer case fluid changed. Shortly after getting her back, got squeal sound, that has a rotational frequency of a drive shaft (fast) as soon as it starts moving, not as loud when above 40mph. also quieter after been run for about 15 minutes. Brought back to shop that did the other stuff, and they confirmed nothing from what they did. THey pinpointed the planetary bearing in tranny. Tranny is factory rebuilt has 50k miles on it. Tranny fluid changed about 20k miles ago (no filter change). THe rear transfer case seal is leaking now too. I'm pretty sure seals don't squeal, just leak, but man planetary gear crap requires taking everything apart in tranny. Does the noise I described fit the diagnosis? I'm into this whole thing about $4500 now, so really not looking forward to tranny work too. Any advice is appreciated,,, the squeal does sound like a bearing but I was thinking driveshaft.
