Re: Aerostar again

Pulling to the right hard. Tire pressure OK. Lugs all tight.

Nothing obviously loose underneath. Bushings look good. Any ideas what to check before I head to the mechanic?

I took it to 2 general mechanics I have used. First one is not set up for alignment but put it up and looked it over. The only think he saw was a possible leaking left ball joint. Took to another general mechanic - also not set up for alignment. (I thought both of them were...) He said nothing looked obviously wrong, brakes not binding, recommended an alignment.

Went to the tire place I use, did an alignment and this is the before and after.... Before alignment (all 3 should be the same photo)

When I drove out, the car pulled just as much to the right as when I drove in. Turned around. Mechanic said the front right tire was were worn on the outside and was causing it to be pulled. Also had lubed it and said specifically that the ball joints and bushings were all fine.

I do need 2 new tires, but surprised that the pulling happened suddenly due to a worn tire....

So my question is..... is the report in these photos show it is was way out of alignment or just a little -- enough to cause the wear?

Thanks, felllers.

If it started suddenly I would suspect a damaged tire, either from hitting a pothole or similar causing a belt failure in the tire. That could cause a pull.

As for the numbers. The caster angles should match on that vehicle. When they don't it can cause a pull. 1/2 a degree difference is enough to cause issues and you have over that. With more on the right side.

Thanks Steve. Looking at the caster, before alignment it was 3.0 left and 3.7 right. After alignment it was 2.9 left and 3.6 right. Does that mean alignment needs to be done again?

The right front tow was -.15 before alignment and +0.03 after. That makes sense to me because the front right tire was worn quite a bit on the outside.

The rear toe before align was -.13 left and -.07 right. After align was

-.24 left and +0.17 right. Is that also something to have corrected?

Sounds like your mechanic un-aligned it . Both sides ahould be very close to each other , I'd be demanding they redo it and do it right or give me back my money . I don't know about where you live , but here all 3 dealers have the proper equipment , and none charges all that much - compared to tires at $150 each .

Snuffy,

Swap front with rear tires to eliminate the "wear" hypothesis.

swap the front 2 side to side and if the pull switches sides, its the tires. pretty simple. KB

I'd say find a real mechanic, and a real alignment man. The caster should be between 2.5 and 4.5 degrees - and within 1/4 degree right to left. The camber should be between +.8 and -.8 degrees, and within

1/4 degree between sides.

The clown that did your "alignment" is a hack.

If the tire is the cause of the pull it will pull the other way if you switch tires right to left, and the pull will dissapear if you switch front to back (the first thing to do when diagnosing a pull, by the way)

It needs to be done, period. He didn't accomplish anything as far as the caster is concerned.

. He made an iprovement on the front tow

You have a solid axle. There is no way to adjust rear toe, but the truck is "dog-tracking". The aerostar has a 4 link coil suspension - a bent component or worn bushing can allow the axle to shift back on one side or forward on the other - causing the "dog track" If there is a significant amount of actual toe in or toe out on a solid axle you have a bent differential housing or axle tube.

I had a problem similiar with a GMC Savana. Did alignments, replace steering box, swap wheels, all on warranty, all to no success.

My daughter borrowed it for a couple of snowy days, lost control and head on into a boulder.

The steering wheel was sideways, the hood in bungy cords, but it drove fine and no more pulling to the left.

After the $9000 repair, is still running straight. Go figure.

Thanks Steve. Good specs - tighter than Ford or the tire dealer. Here's what I got from the Ford dealer. Looks like tire dealer needs to adjust the toe closer to mid-range

Toe Total - Min. -.2 Max. +.32 Toe: 0.06 plus/minus 0.26 Camber: +0.25 plus/minus 0.5 Caster: +4 plus/minus 2

Finally got to the root cause. Worn tire - possibly steel belts moving inside....

Took to local corporate chain shop. Long time people there and I have had good luck so far.

Asked to TS why pulling to one side. Checked alignment and it was off. I said go ahead with alignment. Picked up car, drove 40 feet and no change. Turned around. Explanation was that front tire was badly worn. Had them switch right & left. Now pulled to the right. Tire is the problem.

Nothing lost - it was out of alignment and had to get that done before putting new tires on. But disappointed they didn't test drive it or swap the tires the first time I took it in.

Tire on sale is $59 -- plus another $45 for everything else.
