I have a 96 jeep grand cherokee limited that keeps pulling to the left really bad. I have just gotten an aligement and changed the bearing like I was told to do. I also got new front wheels put on it. Why would it still be pulling so bad?

It's very possible the lower ball joints are shot. Consider installing a new set of Moog lower ball joints. A good front-end mechanic should be able to review and tell you what's wrong. Frequently, there are many zerc fittings that require greasing on Jeeps. Make sure that has been done.

Another possibility is that the front left caliper is bad. The piston may not be retracting fully. This may require replacing front calipers and completely changing the brake fluid. Not changing the brake fluid every 2 to 3 years causes corrosion that leads to shortened caliper and ABS life.

Thank you for your help I will look at all of that in the next few days
