front to back?

[the truck doctor]

hello all,
small Q. does any one know if you can swap the front third to the rear and vis versa on an 80 model ? rear third is roaring very bad in third and fourth gear on the road, reason for Q?

Yes, front and rear diffs are the same on solid axle trucks and 4Runners. I would pull the rear drive shaft and shift it into 4wd and drive a round a little to make sure it is the rear diff that's making noise.... With no load on it, it should be quieter....

If your going to have the diffs out, it's a good idea to tighten up the carrier bearing preload, links to good info:

Really? I'm about two stick to diffs in my truck I haven't run before (welded diffs, steering will suck) so I'll be checking the preload, because I don't want to see those diffs out of that truck anytime in the near or distant future if I can help it!
