Ive got a 489 case 3.55 clutch type sure grip in my 70 duster. (bought it used) i finally made up my mind that I'm not going to screw around with doing the 8.8 swap, as i just hate c-clips. (had an axle exit the truck at work recently....)
so I'm starting to work on the 8.75. i fixed my rear wheel bearings today, which made things a lot quieter. still have the whine/howl under throttle, though. anything above maintenance of speed going downhill gets really, really loud. driving with earplugs or the stereo cranked up is just not an option, either. i like to hear myself think.
so, anyway, here's the question:
if the howling is due to improper gear mesh (according to google, that's what causes it under load), what can i do to fix it?
can i reset the gears with standard tools (i have all the dial indicators, calipers, micrometers, etc from when my dad built motorcycle engines)?
or, better yet, does the Lucas rear axle lube that guarantees to quiet noisy axles actually work?
worst case scenario, i have to pay the local drive line guys 800 to rebuild this thing. id prefer not to dump that kind of money at this point in time if i don't have to.
long story short, what kind of inexpensive fixes are there, or is it just shot?
