need help on identifying the jolt...SLASH...jump on my 98 4.0 XLT 4wd. It jolts/clunks from a Stop'N Go. Feels like it coming from the tranny and drive-shaft right under the floor. Nothing really wrong but am concerned. I've heard it might be the "Slip-Yoke" and needs greasing? if so, please elaborate..ran out of things to maintain and need something to work on, KOOOOL Db40-Denver

I have the same thing on my 01, I always thought it was from being lifted, mostly the driveshaft has play in it but thats how I bought it and will eventually look into it more. If you come up with an answer let me know. If I get it befor you I'll let you know as well.

Advised it was the Slip-Yoke, needs greasing inside the boot. Kool )
