I have a 99 Escalade that pulls to the right, requiring slight pressure on the steering wheel. I had the front end aligned and there was no change. Assuming the alignment was done correctly, what other issues should I look at as the cause?

Without a doubt wheels, if you bought aftermarket rims or whatever thats ur first thing to look at, also important is the tire, cheap tires will pull,its a simple fact....even if u have nice rims and nice tires if they werent mounted perfectly ull get some pull....

Swap the frt tires to see if the pull goes the other way. If it does- tires are your problem. 99 Esc. are known for their pull.
