Odd ride height on 88 S4
What would cause ride height to be different at each wheel? Front drivers side sits 1/8th lower then the front passengers and right rear sits lower by ½ then the left (drivers) side.
Hmmmm….
Table is now open for discussion.

Tim-
Each wheel is independently adjusted at the spring. Several threads on this, plus a good write up at
<a href="http://www.928.org.uk/height.html" target="_blank">http://www.928.org.uk/height.html</a>
Need the wrench, Steve J. put me on to Motion-Pro #08-0029 "Mono Shock Spanner" in addition to the UK one (the Porsche one has to ordered, no idea how much).

Thanks Donald...
...for the tip. I'm sure you're right. I'll read through the posts, buy the tool and get back with the results. Question though...how full should the gas tank be when measuring ride hight for that corner or does that have any effect at all?
Hmmmmmm?

T,
Pick one or two...
1.)Ride heigth was adjusted by 4 different people.
2.)Was adjusted on an uneven surface.
3.)Springs or shocks are giving it up.
4.)Somethings bent.
5.)PO had a flat, put one new tire on and left the other three with 43,000 miles on em' alone.
Seriously, just do the adjustment and see what happens.
Remember, don't raise the driver's front a whole half of an inch all at once.
Raise it a 1/4" then make your other 3 measurements again to see if things have changed.
I don't know if measuring the springs in the 'loaded state' will be accurate or not to see if they are the problem - ask a guru -. On the other hand, there has to be a marked difference if you unload the shocks and springs. That is if the alignment stories hold true. Awhile back, Snow did his leveling magic he might help here. Mine were well within spec .
Only thing I noticed is that if you don't pull the tire/wheel it will be a knuckle buster, again the car should be loaded- I think like the alignment you are supposed to put weight equivalent to the drivers weight in the drivers seat. GURU's? Also my 82' does not have adjustable rear perches.
Good luck.

Tim-
I adjusted all four at one go, then drove to settle the suspension before remeasuring- I simply screwed it to the max, came back down an equal amount of turns and it was within tolerance and level side to side.
Doing one at a time may be more accurate, doing 4 worked for me. I adjusted up a net (post settling) 2 1/4" on front left, 2 1/2" front right, 1 1/2" rears. Had I done this in 1/2" increments each corner before driving the recommended x miles (I found it settled after +-20) it would have been an arduous, drawn out affair-probably still in progress given the wheel assembly removal/installation each time.
Following I used Wally P.'s method for toe-in measurement (on Nichol's site) which showed 1/4" slew-foot post (did not check pre, so cannot say if it changed).
Did not bother about fuel, or windshield washer fluid, levels.
I expect it matters but do not give a toss.
Really not hard at all and a procedure I will do on an annual (or so) basis.

Don,
Thanks for the info...
Discount Tire rounded up a full set of Khumo's which go on tomorrow A.M.. So now its out with the measuring stick. I'm still going to do it driver weighted and fueled, though I don't plan on corner balancing as Snow informed me there is 40 kilo's of leeway side to side.
This method seems to be the quickest and a month or even quarterly check/adjusment would keep the collar from welding itself back in place. And thanks for reminding me of Wally's Nichols post.
John S. and Pattycakes.
