so my rear end was like this for a while now and i don't know what exactly is making the sound. Every time I tap on the gas while driving it clanks like something is loose inside, and i can spin my drive shaft side to side like 1/4 inch

 

any ideas??

 

yah it was fine when i got it, when i started driving hard is when i noticed it.

 

so im going to be rebuilding my rear end and want to put an LSD in it, just wanted to know which one is worth getting, truetrac any good or may be ritelock??

And is it worth doing a rear disc brake swap???

If you got the know how disc conversion is very worth it.
