well heres the story i dropped my rear sub assembly so i can replace the diff, then when i finshed i drove it and a strange noise like something was jumping or shifting around had started from the rear right, when i inspected it the right rear shock was blown, so i replaced the shocks and the noise somewhat went away. the noise tends to only start when i hit small bumps or apply gas then let off. my theory is that i might have left the bolts that hold the rear diff and sub assemlby loose and that is what is making the noise, i am going to check it out this morning but i wanted to see if anyone else had any ideas just in case i am wrong.
