Diffs and Diff cup Probs!!!
 

Someone told me that a cheap but effective way of locking your diffs is to fill them with J-b weld. can some one help me with this or let me know if this is true.

Also yesterday I was running my truck and the diff cup Twisted right off the shaft right next to the gear box. I never hit anything or crashed it. and nothing a binding up it all rolls freely.

i believe the jb weld is normally used to lock a centre diff. locking the funfactor diffs will more than likely have an adverse affect on the handling, depending on what u use it for... this would apply more to the front than the rear.

i packed mine with grease after filling the diff casing holes. i have a kinda limited slip effect going on at each end now. if u are trying to stop the inside front wheel spinning, then try making up a rear anti roll bar, all the mounting points are already there... it worked well for me on my rally.
