Title: Shaking problem
Post by: Slammed83 on January 15, 2011, 11:06:11 pm

Hey guys i cant figure out whats wrong with my truck. It idles normal then when i shift it it kicks hard, But thats because the idle is high because of the electric choke. If im going down the road and go over 1200 rpm the truck gets a death shake. I did a burnout last friday then it started acting up. I tried one today also. Last week the passenger side spun and driver didnt. Today it was the other way around. So im wondering if i didnt mess up something in my rear end. What's your guys opinions?

check your engine mounts and trans mounts to ensure your drive train is secure.

Check your lug nuts in all wheels (tighten)
 
Make sure your wheel isn't cracked

Once it starts to shake does it happen at a speed or rpm. Try to get it to shake going down the road note what Rpm its turning. Stop then put it in first and match rpms see what it does if they ain't to high

Well i got on it this morning and it made a ping-ing noise. So im checking my torque converter to flywheel bolts.. And transmission cross member bolts.

Check ujoints had one fall apart it would ping and the driveshaft would make the ping louder

crawled under there about an hour ago. I am really suprised it hasnt broken but the transmission shifted to the left, And you can see where the drive shaft has hit the heat sheld for the cat.. And where it bolts to the rear dif, The bolts were loose.

Why did Irish get all the votes on this one?  
LOL
I think everyone got this one right--loose u joints due to the ubolts being loose and broken insulator Trans mount.

I had that problem before, the noise scared the crap out of me when the driveshaft hits the cat heat shield when I turn right, and each turn of the driveshaft created another bang.

I agree with SgtDel, lol

Makes you want to go front to back and top to bottom torquing every bolt now, I bet.

It was the pinging Sarge. That's what threw me. I've heard that sound before.
