any more updates for this beast???

No updates yet. I've got plenty on the to-do list, just been focusing on other things. Hopefully this summer I can get some new projects done.

Still not sure on the noise. It's not really a thumping, more of a rubbing rotational noise. It sounds like what I would expect a bad wheel bearing to sound like - especially since it is more pronounced when I'm on a left curve and not a right. But neither rear wheel wobbles and no other visible damage (like torn boot).

PRECISELY the issue I have currently. I have a "new" 4.10 lsd in the back and new half shafts and neither addressed the issue. My next step is going to be the drive (prop) shaft and new wheel bearings.

Please let me know if you sort out the noise in the mean time...

my worn top shock mounts *could have accounted to the noise as well. when i had the rear out i replaced all my bushings mounts and anything rubber with urethane. replaced wheel bearings and rebuilt the half shafts. trans is comming out soon to do the ltw fly conversion and ill do the guibo center bearing and sloppy assed shifter too.

Hey JP, now I'm cool like you are.

Hi Alan

Edit: Hi everyone else too. I was pretty surprised to see the view count on this thread! I'll get around to finishing what I started someday but for now I'm just keeping it on the road and enjoying the driving experience. Not sure when I'll have enough funds to get the suspension stage underway but it definitely appears to be later rather than sooner.

I've developed some obvious signs of wear on the various suspension components in the last few months. I'd planned on upgrading as I repaired like I've done with the previous stages, but I really need to address these issues before serious damage occurs and unfortunately I can't do any nice mods while I'm under there.

Cheers.
