Rear differential "slack", is this bad?
Rear differential "slack", is this bad? I noticed when putting in my U-joints that my rear diff has quite a bit of play in it. I believe this is why I get a "clunk" sound when I shift, its the rest of the drivetrain catching up.
Is there anyway to fix this conveniently? Is this bad?

That all depends. The "slack" you are talking about is your backlash. You would usually want this to be around .008" - .010" (Assuming you have a stock 7.5" 10-bolt). It is measured off of your ring gear. Excessive backlash is a good sign that you are on borrowed time.
It's a very easy fix... time for a 9" lol. Seriously though, it would probably require new gears, an install kit, and someone to install it.

The majority of the "slack" you are describing comes from where the splined axle stubs slip loosely into the side spider gears in the diff. If the gears were responsible for it, they would be screaming bloody murder. This also makes the clunk.

Verdad Gallardo So what you're saying is this is normal and I'm overreacting because my rear isn't making any other noises.
My stock 10-bolt always had a bit more "slack" than I thought it should, but it was dead silent. My Strange 12-bolt has less slack, but the gears whine like a banshee - granted, I know the two aren't related, but that 10-bolt was good up until the day I sold it. I'm not sure what has happened to it since (it went in a car with a turbo and an automatic transmission), but I wouldn't worry too much about it.
