What is causing the steering wheel shake?
I did a search but really didn't find what i was looking for.
I just purchased a used 2007 silverado with 22,000 miles. The truck has already been lowered and sitting on 22" rims. When i test drove the truck i noticed a slight shake or shimmy at free way speeds, 60 -70 mph. The dealer told me they would have the alignment and the wheel balance checked and i would pick it up on the next day, i still haven't taken it home yet.
Next day arives and as i show up at the dealer my salesman comes to me and says something still isnt right with the truck. He had just test drove it and said there was a steering wheel shake under hard acceleration going up hill but not down hill. So i test drove it my self. Went up the hill under hard acceleration and felt a little shimmy in the steering wheel. I turned around and accelerated hard down the hill and suddenly the steering wheel shook it's head like a wet dog.
Never got up to freeway speeds, just pulled it into the dealer ship and started looking it over. Noticed they replaced the right rear tire and put the wrong size on, its now a 305 instead of a 265 like the others. Is this causing the problem or is it something far worse and maybe somethign with the lowering work that was done previousely?
Needless to say they said they will make it right or i don't have to buy the truck but i really like it and want it, need it. Please advise!

how did they put on the wrong tire? the size difference is a lot! but I wouldn't buy something with that kinda problem, too much to worry about, such as safety for yourself and others, and then warranties and parts wearing out quicker than they should.2010 Equinox LT

There are many variables with this type of issue.
Recently, I changed out the 265/75R16 tires for a new set of 305/70R17 Goodyear Wrangler Silent Armor A/T/s on my 1994 Silverado.
There had been a slight shimmy or shake prior to the tire change. New tires cleared that up for me.
Alignment won't help if the tires are out of round. Two new tires up front may make a big difference.
On the other hand, on a truck with a solid front axle, a steering stabilizer shock really helps a lot. Not sure if there is anything available for a newer truck with IFS.
