Hello everybody. I have a 2003 suburban ls 1500. I recently started experiencing a shimmy from rear end while drivig between 40-50. It happens when I apply light pressure to gas pedal but once I reach 50+ or let off gas it goes away. I do have custom wheels & tires but had them rotated and balanced a week ago. Tires are in great condition, recent alignment and proper air pressure. If anyone can help, I'd be grateful.

 

Welcome to the site kingsmoke, thanks for joining us!

 

Thanks for the warm welcome.

 

remove the rear driveshaft and check for a tight u-joint

 

Will do.

 

Well I figured out the problem. Torque converter is going bad...well say bye bye to a few hundred bucks smoke...

 

depending on how bad the tcc shudder is;you could try a complete trans fluid exchange with gm dexron fluid. do not use aftermarket fluid.

 

How did you determine that?

 

A guy I work with drove the truck and immediately knew what it was. It helped that he had been a tranny mechanic prior for 15 yrs. Then google to back up his explanation.

 

Really? Whats considered a bad shutter to you (currently not a violent shutter)? What % chance would you give that this would work being that its been going on for close to a week?
