Well I mentioned this a while back that my van had some kind of weird whining sound which I've actually heard from quite a few vans with the A670. I noticed it only does it in 1st and 2nd. It has been making this noise since I got the van nearly 80k ago. Trying to put in control arm bushings today I found that I could move the axle end inside the trans up and down a little bit while it is fully inserted.. I'm guessing the gears in the diff on this side are fried.. I also noticed when I would turn left under a load that there is a sound like a wheel bearing going.. My guess is this is the noise. That said, short of pulling the trans what is involved with replaced the diff bearings? I can get another trans for 100 dollars from the local salvage yard.. I may just do that. Thoughts?
