50 to 55mph shaking HELP!

[Gui272]

I purchased new tires back in april and thought i've been having major problems having them balanced.

Today i got them road forced balanced and the tires are ballanced and have no defects at all. The bad part is i still have my shaking from 50 to 55mph

Any ideas what to look for? I feel it in the steering wheel and in the seat. It's not violent at all. It just feels like the tires are out of balance.

The tires are BFG AT 285/70/17. They said the tires are in good shape with no problems and all 4 wheels are fine also.

Thanks!

I had a that same problem but at 40-45 mph and I checked my tire PSI and it was low (32 ish) so I brought it back to 55 PSI and is has not happened in about 1 month.

Not sure where yours was done but I had tires put on my previous car and had the same issues. Took it to a mechanic later on and turns out the genius at Pep Boys put one tire on backward! May not be your issue but just a thought

Tires are good and on right. I just had them re balanced yesterday. Im sure its something with the truck. I guess check out all the front end stuff and see if something is loose.

Any other ideas?

I bought my 06 with 82K miles in April 2010. When I bought the truck, it seemed to drive fine, but it needed tires. I had the original tires (18" Continentals) replaced by my local dealer and immediately noticed a slight shake at highway speeds after picking it up. Took the truck back to the dealer, who rebalanced the tires, but the problem persisted. I took it back to the dealer again, who felt that the carrier bearing wasn’t shimmed properly and was to blame. Again, this did nothing and I gave up on them. I took the truck to my buddy’s shop for a full brake job and while he was doing the rears, he found that one of the parking brake shoes had rotted so badly that it came off its pivot mount and was rubbing the backside of the wheel studs, which would cause a vibration. Well, following the brake job, the problem persisted so I took the truck to a local tire installer and had the tires road force balanced. The tech. found that one of the wheels was slightly bent and blamed the shake on the wheel. I have yet to replace the wheel because I plan on putting 20s on. If that solves the issue great, but something tells me it won't.

Check ball joints and drag link I had the same issue about 6 months ago with mine
