Well, I went last night and traded my honda accord in on a 2001 Seville STS...loaded with everything. It has 55,000 miles. I have to take it back next week to get aligned, but that seems to be it.

WOW!

What a change.

Many happy miles,

Congratulations and many happy miles to you.

I am curious about the need for an alignment. Since there is no provision for adjustment other than toe, what kind of a correction is needed and why?

Now THAT'S what I call mov'in on up.

Are you sure Jim? No camber? I thought caster was adjustable by elongating the strut mounting holes?

You must be in shock! STS v. Honda Accord :lol:

The strut has to be removed to make any adjustment to the top or bottom mounting holes. It is not like there are cam-bolts at the bottom or built-in slots for the 5 thrust bearing holes at the top.

The hole location / size and the OEM parts are designed to bolt in and the geometry will fall within the specified angles. If the geometry is not correct, the parts are either not OEM or something is bent.

Trademark? Typically an alignment is needed to correct pulling, leading, tire wear, and toe problems. Not necessarily shimmy.

Shimmy could be caused by many things:

1) a bad tire (out of round or edge heavy on one side) that "may" be corrected by road force balance

1a) a bad match between the wheel and tire

1b) a bulge in tire from a damaged steel belt

1c) an inferior or worn tire (something that you often get when you buy a used car)

1d) a "second" or "blem" tire from a discount tire outlet that has flaws, (ie, the reason why you pay less) the best tires go to primary outlets

2) a tire out of balance

2a) A tire that was balanced by a tech that is inept (that is still OUT of balance, see Rangers experience)

3) a bent wheel

4) a wheel with damaged lug holes (enlarged, the lug bottoms before securing the wheel)

4a) we have even seen BENT lug studs (see archives)

4b) inferior aftermarket wheels

5) improper tightening or torque (see JimD's recent recommendations)

6) debris on the mating surfaces of the wheel or rotor (very common)

7) a damaged/worn tie rod (inner or outer)

7a) damaged or worn bushings (control arm, strut rod)

8) a physically loose rack (search archives)

8a) an internally loose rack (see Regis repair)

9) a bad strut allowing undampened wheel movement

9a) a bad rear knuckle radiating vibration through the car

10) a bad CV joint

11) a bad engine mount

12) run out of rotor/wheel assembly

13) and the worst it could be is a bearing/bushing in the transaxle (see Logans repair)

I hope I didn't forget any causes, but I am sure there are other causes..

Before concluding that this need for an alignment is a "trademark shimmy" most positive minded people would typically run down the list of potential causes before uttering the term "trademark" and giving up... Without detailed analysis, to right away conclude to a "trademark" shimmy is simplistic thinking.

There are terms for this type of reaction, gloom and doom, negativity, glass is half empty, the sky is falling, push the panic button, finger pointers, knee jerk, etc...oh and my favorite lousy mechanics drawing assumptions as they are too lazy or just plain overwhelmed.

Yes, I understand that, which is why I said "I thought caster was adjustable by elongating the strut mounting holes". What about camber?

It really pulls hard to the left. I have an appointment on Tuesday for the alignment and a couple of other things. I will post some pics when I get a chance to take them. If you would like to look at a similar car....look at 02 STS's pics of his Caddy(you are the reason I bought mine because I got jealous) :)

.... What about camber?

You would have to elongate the upper of the two bolt holes at the bottom of the strut (strut to steering knuckle). And I don't see how you could do that with a file; that strut material is pretty thick down there. It would have to be easier and faster to move the strut to the bench and use a power tool to modify the hole.

I don't really quite understand this concept of "net build" and "non adjustable" alignment.

Is this to say that every part must be machined completely perfectly from the get-go, and that by default, the car is "perfectly aligned" as assembled? There's no adjustability designed into the suspension...except for "manual" adjustment by enlarging bolt holes? That seems pretty crude.

.... That seems pretty crude.

Maybe it speaks to maintaining control over manufacturing tolerances in a production line environment. Plus, GM (and others) holds their parts suppliers to some pretty rigid quality standards.

Remember our guru's favorite song "When you buy OEM parts, GM has done the testing; when you buy aftermarket parts, ....."

As far as steering geometry is concerned, 99% of the motoring public could not tell the difference if the parts fell together at one end of the spec's vs the opposite end of the spec's. And the front end spec's. on the '98 - '04 Seville chassis are quite broad. Perceived "front end' issues are far more likely to be caused by tire issues than alignment issues.

camber is top of the tire going in/out. caster is top going forward or backward along the centerline of the car. my 96STS strut can allow for camber changes. the knuckle mounting pad can slide in/out. doing that will also change the toe slightly. not sure if the strut design changed from 96 to 2002? probably when the body changed in 98.

Thanks for the info....I hope this dealership can do something about it because I noticed it is wearing the side of the tire.

Mine did this and needed a ball joint..... Don't be surprised if you need one.
