First of all, my truck has no vibs at all, no nibbles- NOTHING but smooth like glass- loving it!!

SOo its not that I m panic or anything...just curious..

My truck basic info- Superchip (87), '04 FX4 Screw 18", rear replaced clutch pack...

I noticed once a while that from dead stop at traffic light or park lot...when i put my right foot VERY light tap onto gas pedal (FORWARD), it felt a bit shudder for like 1-2 sec it only happen from dead stop...

If I normal drive like when traffic light turns green, moving truck normal and it has no shudder....it only happend if i move my truck VERY SLOW like tap on gas..

So is it normal ? do you guys have similar like mine??

Thanks!
YOMAN!

 

I just had mine in the shop and the service manager said it was the clutch packs.

 

Yea, my rearend replaced clutch pack and its much better but i m talking about for 1-2 sec shudder if you light tap on gas pedal..thats all but i was told its possible need greased yoke by driveshaft..


YOMAN!

 

They greased mine, but they had to order the clutch pack. It's especially noticeable when turning. He said it is due to the limited slip, but you shouldn't feel it shudder.

 

mr friend brought his to the dealership and the said it had something to do with the clutch packs
