Also mentioned by Marcus earlier as a spreader bar in this too long of a thread.

Not completely clear, but understand it to simulate highway speed, which as you said, causes more force and toe is more needed. If toe is set static without bar and the parts are warn out, at highway speed the toe will become incorrect and cause pull, correct?

Tram's suggestions are very logical and well thought out.
I was busy with my head down in the question... his suggestions are good for the overall attack on the problem.

Just need to put pants and a shirt on, then can get on it. Don't think anyone wants to see me in a union suit.

(No sense getting cloths dirty if not going out in public.

That thread about ' spreader bar' had some bad information in it...
for instance.. ' it loading the suspension'...
it is just a long ruler which can measure across the width of your car in front of the wheels at a certain height.... it can have nice things like little tabs which will set in place.. because you are not measuring the distance between the wheels... but the difference between straight ahead and what you want to compensate for tie rod wear, etc..

Is your Master's Degree going to be in Mercedes Repair ?

Yes AND tire wear....and also should make the tires squeal when turning corners...

Adriel · #67 10-13-2015, 06:37 PM

leathermang, will reply, as very interested in your thoughts/entertainment.

Have something interesting:
front left: 35pst
front right: 33psi
rear left: 33psi
rear right: 31psi

Now going to swap tires, unless someone says no.

leathermang · #68 10-13-2015, 06:56 PM

LOL... you were LISTING to the right due to tire pressure...
yikes...
yes to the tires...
Did none of those ' alignment guys' set the tire pressure before starting ?
of course I do not know that it would only show up under ' decelerating'.....

Well, we shall see shortly that I now have had a snack (have low blood sugar condition).

I did check the hight, the front is 30.5", the rear left is 29.5", and rear right is 29". But, the pump isn't running, so not F.S.M. correct.

I would thought the technician that did it last should have known, being older.

Let us not jump yet.

Oh, and the rear tires only turn a half turn. Without tires, can't turn the rotors. Double checked parking brake is off despite it not fully working on a hill.

Front left turns three and the front right turns three and a half.

Now off for a drive.

That's normal. What you are looking for is a lot more drag on one side than the other.

Thank you so very much for replying!

So then, the fronts need adjusting, since the left is slightly dragging more than the right?

leathermang · #72 10-13-2015, 09:42 PM

I think he meant a "LOT" more.... so they are close enough as far as I can tell...
but at some point if this veer does not go away... you need to recheck the bearings and put new pads on both sides ...

3. Ditto the rear.

Road test the car with the pressure adjusted and tires swapped side to side and report back with your findings.

Let's eliminate possibilities one by one.

1) Done. Don't think made any difference as pull to the right is still there, especially on the freeway.

2) Slightly more drag, about a half turn less, on the left. Pads are both about a quarter inch thick. Did they have a center groove? Rotor has about a 1mm or so lip, even both sides.

3) Rear drag the same. Forgot to check rear pads, but rotors looked good.

So, the pull to the right is the same even when removing pressure on the foot feed. It gets worse on the freeway, so toe adjustment?

Does camber make banking turns more confidant feeling? To me, something doesn't feel right based on almost three years of ownership.

Okay and to me, should be pulling left if significant, so going to ignore.

So, what is the next step?

Oh, by the way, the front end makes groaning when turning at low speeds. Always had a slight clunking both sides when braking hard (not easy braking) and engine shutoff, so it is bad engine mounts. Did fix it for a short while, but came back. I have accepted it as inevitable.

leathermang · #75 10-13-2015, 10:00 PM

How did you fix it for a short while ?
