Pulls Right Again!

[rescuerandy2]

Just bought an '03 MM and am enjoying the ride but it pulls to the right at 31K. Had a 96' PI Crown Vic, '03 Crown Vic LX Sport, and an '02 Crown Vic all pulled to the right. That is 4 in a row and I swear I do drive on the left side of the crown too. My aliginment guy says it is just bad luck. What is going on? Thanks, Randy.

You need an alignment from a different shop.

Sounds like your "alignment guy" doesn't have a clue. Find someone who knows what they are talking about. And, have them use Carfixer's Alignment Specs ... \/\/\/\/\/ below.

The inside edge wear of the front tires is caused by 2 things: negative camber and negative toe (toe out). Caster is not a tire wearing angle. The outside edge wear can be caused by excessive toe in and aggressive cornering.

Factory camber spec is -.5 degrees or- .75 degrees
Factory toe spec is -.15 degrees or- .20 degrees
(BTW, this info came from their website which is updated periodically and may differ from previously published material, such as cd's and paper manuals)

That means your alignment could have -1.25 degrees of camber and toe out of -.35 degrees and still be in the "green". This will wipe out the inside edges in <20K miles IMO.

All of the MM's I've aligned (about 10) had at least -1.0 degrees of camber and always toe out of -.10 degrees or more from the factory. That's why almost all MM's you see have excessive inside edge tire wear.

For best tire wear, here is what I use on all MM alignments:
Camber: 0 to -.3 degrees.*
Toe: Zero degrees.
Caster: 5-6.5 degrees positive with .3 degree lead on the right side.

*Camber can affect cornering feel. The more negative camber you have, the better it will handle corners. Most drivers will never feel the difference, especially on the street.

Please don't shoot my alignment guy! What I meant to say--all the previous Panthers would be pulling to the right when I bought them. My alignment guy would fix them with no problems. But, all of them to the right? Thanks, Randy.

Are you sure it isn't just the roads you are driving on. If they all make a right pull, perhaps this is the problem.

If your front tires are not unidirectional, then cros them, too. But definitely do your next alignment under Carfixer's specs.
