rear end going bad?
Hey guy's, got a question for ya! I have a 1990 F350 dana 60, sterling 10.25, 460, 5 speed.
Over the weekend I had a death wobble. I, rebuilt the king pins + shimmed, steering stabilizer, new front wheel bearings, castor angle set, aligntment, tire rotate, rear end wheel bearings done cause they were going bad, all new U joints front and rear shaft.
I still got a small wobble or shimmy at about 45, anything above or below really drives smooth. I feel like the hop shimmy thing is coming from the rear end.
Tonight I pulled into the shop, and I didnt pull far enough forward after I parked it. So I hopped out and through it in neutral, grabbed a rear tire and pushed it forward. I heard and felt a light "clunk" in the rear. This is not good Im sure having blown a dana 60 ring and pinion, plus the spiders.
What could my clunk be before I remove the cover? Not too familiar with these rear ends, could the spiders be headed out?
The truck drives straight as an arrow, no shimmy, when I round a corner on the freeway, thats really long, I get the shimmy.
Thanks, Matt

First thing I would look at is the yoke on the pinion.
Make sure the nut is tight and the splines are not worn which would let it rotate on the pinion slightly.
I think I have replaced my yoke 3 times in 440,000 miles, but I do haul and tow a lot.
Did you rotate the tires after the front end work?

I rotated them after the front end work. Ok Ill check that, the previous owners were VERY harsh on this truck, so that yoke might be a possibility. Ill take a peek at it,
what should I torque that yoke to if its lose? I think these just have shims to set the preload on the pinion correct? not a crush sleave, so just torque and go is what im thinking.

ok had sometime today finally, I picked the rear end off the ground and with the tranny in gear, I rotated a tire one way, the other spun opposite. The drive shaft is not moving.
But as the tire was turning I can hear this cog wheel sound.. like the spiders contacting one another. I feel this on both tires, the sound is there no matter which way you turn it. I am strongly thinking this is the spiders going out.
What do you guys think? help! If the spiders are bad Im just gonna weld them up since Im getting a locker for the rear at the end of the summer, along with new tires, but just to make it work till then.

does sound like the spiders, but you need to pull the diff. cover to be sure, wouldn't get to excited to weld the spiders till you see what condition your gears are.. they might make it to the end of summer..
