I recently replaced my rotors and drums on my truck........I was noticing your typical "THROB" in the pedal. Now I'm feeling a "SHAKING" over almost the entire truck.
I noticed when I hit the gas from a stand still, the shifter for the auto and the 4wd shifter move a lil from the torque.
My question is this,.,,,,has anybody else had this issue? And I'm thinking it might be a motor or tans mount. Any ideas?

 

I'd check motor and trans mounts first. Sounds like something loose.

 

yeah,,,,sometimes it's worse than others....if the road is real bumpy, its BAD

I was thinking a mount too

 

Had the same thing in my 01 RAM. Steering Stabilizer!! Take it off and run it and apply the breaks... Did it stop shaking?

 

I'll check it out tomorrow and let u know...thanx

 

This is quite normal.

 

My 4wd shifter also moves a little. I am guessing if you want to dampin that you can use a poly trans and motor mounts. You will feel more vibration in the truck tho with poly. Or at least i did with my jeep.

 

As far as the brakes go. After you replaced the rotors, there should be NO pulsating pedal. I'm afraid you might have warped rotors. What brand did you buy?

 

well I replaced the steering stabilizer today......almost 100% of the shaking gone...I DID notice that my tie rods were in need of replacing....a lil looose........

other than that...I blew my plenum gasket on the way home today....while doing about 40mph, I punched it, it downshifted and started "howling" a little bit..loss ALL *****......would barely make it uphill and barely made it pass 40 while downshifted.......
I'm almost positive it's the plenum gasket.....would my OTC GeniSys 4.0 say whether or not it was the plenum gasket? It tells the fuel/air ratio %......got mad spark knock too.......ZERO *****

 

Something went...... PCM won't set a code for it, but, it will whine about running lean, if it can't compensate for the additional air.
