Front end alignment review please BMW 325i
*EDIT* This has been corrected. The advice in this thread fixed it.
Thank you upfront for any observations/advice. We had a front end alignment performed on a 1994 BMW 325i. It had a pull to the left. While the data sheet shows that it was aligned it to within specs, it still has a slight left pull. My theory is that it was out of tolerance to the left and that the shop was able to bring it to within acceptable spec, but still to the left side of the within acceptable limit, thus leaving in a slight left pull. Tire pressures are good, no previous accidents. Since I only know enough from the data sheet to know that all is in spec, can someone confirm or debunk my theory about why I still have a left pull?

Could be the tires. I had this issue. They swapped the front tires and it went away.

Hi - to be clear the actual readings are good, specifically the caster and camber which respectively will have the largest effect on whether the vehicle wants to travel in a straight line. When you say 'pulling' do you mean driving down a straight road with very little crown, you take your hands off of the steering wheel and it starts to go left?
OR is the steering wheel off- center when driving straight? If the rear wheel toe / center line is proper - which by the printed read out above; it is then the steering wheel is not centered.

Always swap the tires first if a car still wanders or pulls after an alignment. That's the two front tires, left/right. You need to eliminate that possibility before going further.
I'd say that even if that corrects it, rotate the tires front/rear, putting the swapped front tires on the rear on the side they were on before you swapped them. Radial tires should not generally have their direction changed halfway or part way through their life.

No question it could be the tires as the last part of this, but need to establish what 'pull' you're experiencing.

I also say swap sides with the front tires first.
If that's not effective, bring the left rear camber, and toe closer to zero by about .4 degrees each.

Glad you got your answer and that it's sorted out.
I would just add, equalize all 4 tire pressures, then swap tires in pairs. Also, your right rear camber was pretty far out of spec. |
