99 Suburban has severe front end shake only when towing.

Asked by Jun 14, 2014 at 06:42 AM about the 1999 Chevrolet Suburban C1500 LT

Question type: Maintenance & Repair

Truck's front end is solid, it's been to several front end specialist, some with 45
years experience.  Truck's steering wheel and dashboard shake violently ONLY
when towing.  I tow, or I should say, try to tow a small jon boat trailer( Ventura),
at 45mph, the front ends starts to shake. It gets worse the faster I go. Shake
lessens when speeds are 40mph and below. Ventura trailer is brand new.  I
have another small homemade trailer that I was towing and though it was a
problem with that trailer but, it happens when I tow anything at all, no matter how
light the tongue weight is.
I have a ghost!  Please help. :(

Possibly a out of balance tire or one that is separating internally. Having them balanced will tell if this is the issue or not.

Thank you, The tires have been balance twice to make sure that wasn't the issue. Internal separation is something I hadn't thought of. I had planned on replacing the tires any way. We discovered the tires came off another truck that had been sitting in a salvage yard for quite some time, and are try rotted between every thread. Thank you very much for your input. Great appreciated. I'll respond back later this week, once I replace the tires.

Ok. With dry rot in the treads I would bet on internal separation. Look at your wheels. Does one of them have a lot of wheel weights on it. If so they had to add all of these to balance it because of internal separation of the tire. Went and had mine balanced the other day and they had to put 10+ ounces on to balance it. Future investigation showed that the tire was separating on the inside. It also had small dry rot lines in the treads.
