Ouch, sounds like you had fun JK

Anyway, check clermontmotorsports.com or allaboutfunhobbies.com for part number 08059, they will have better prices, faster S/H and better customer service.

Check to be sure your rear drive shaft's U-Joints are firmly connected to the shaft coming out of the center transmission and the rear differential. I had a similar issue with my front ... one of the small M4x4 set screws fall out while driving and had to go buy a new one (set of 4 was $1.25). If that's the case, take them all out and use some good blue Loc-Tite on them all and re-tighten them down so they don't pop out.
