Whole truck is bouncing

When I first start up my truck and start driving it starts bouncing up and down. I recently got Matt's SRL and think it might be my oil isn't warm enough for the injectors at that point. Once my temps get a little Warner it stops and runs great. I could be completely wrong and any input would be great.

The truck itself is bouncing not the rpm's.

Odd! Could be teeth broke on the pinion gear or bad u-joint but that aughata make a lot of noise. Did you check your tires for aturned belt/damage?

Whole truck is bouncing

When it's warmed up it runs great and doesn't bounce at all. It's only when the temps are still low.

My truck is a bit bouncy when it's real cold it's worse. lol Once my 38" tires warm up and get round again it's fine, can't wait till summer

Sounds like you have a severe case of stiction, what oil are you using??
5W/40 will surely help but not so sure enough ? strange thread ??? ? ?

I'm using Rotella T. I think it's 15w40 but not 100% sure, I'd have to check my bottles when I get home in the morning. I've thought about trying revx to help out and a fresh oil change.
