Re: astro rear end noise
Digging this one back up. My 93 whines pretty bad. Last year I replaced the outer bearings and seals. I didn't think to check the axles for pitting or even see if I could move them from side to side. My question is, "Is it common for those outer bearings to go bad and wear into the axles causing this humming?" I will put it on some stands and use a broom handle or stethoscope. If it's the outers, I can replace the axles and bearings. If it's the differential gear, pinion and all of that I am pretty much screwed. I think a replacement or rebuild wold be in orders. At 200K, I don't think the van is worth a 2 to 3K investment to repair as one shop told me.
