Rotationl squeak in forward and reverse when trucks barley movin

Ok so I had this squeaking and strange noise coming from under my truck it's a 08 tacoma 2x4 it sounder like rocks inside my rim and a squeaking noise called the dealer and said it sounded like the carrier bearing so I replaced it along with the u joint since I had it pressed out already. Put it all back together and it seemed like the noise had stopped but is still doing it in reverse and it's Farley loud. Any ideas? All u joints were tight and has no slack in them.

 

The u joints may be tight but that doesnt mean they have grease in them. Id replace the front and rear ones or whatever other one you havnt changed already. The pre runner ones are not servicable i dont think.

 

Sound something like this?http://www.tacomaworld.com/forum/2nd-gen-tacomas/292949-reverse-squeak.html

 

I changed them all last night and it solved the problem the one on my rear end had a bad cap on it that was dried out
