Wheelbase
 

My Blazer has always had a wheelbase 1 inch shorter on the passenger side. Is this common?
It was noticeable when I first got it - all stock tires no lift, the distance between the fender and tire was different. I have installed a 2 inch suspension lift and 33 inch tires, hacked on the fender some for clearance on the passenger side but was not necessary on the driver side.
Reason for asking it has always pulled to the right. Hoping to correct it some way.

Are you saying the wheelbase is different, as in the distance between the front and rear tires? Or are you talking about it sitting lower on the passenger side? If your wheelbase is actually different on each side, I would say you have problems. If it is just sitting lower on one side, from what I have heard these old Blazers are known for that. The leaf springs get weak and sag, mine does the same thing. You can have them re arched, or buy new springs.

The wheelbase is actually different. It doesn't cause any tire wear, the only thing is it pulls to the right. Not excessively, but if you let go of the steering wheel on a flat road it will drift to the ditch. I've seen on CK5 where they redrill spring packs or perches and plates to move the entire axle forward. Was going to try that on one side but that won't work, need the stabilizer. Had several shops look at it, even paid one who said they straightened the frame but front to back measurements wheel to wheel is 1 inch less on the passenger side. Guess it's something I'll have to live with. Long trips, such as to Arkansas it gets tiring.
