A pic attached of R.F. Tire. Both RF and LF have similar wear patterns on the inside. I replaced the Front Shock Mounts and Shocks 20K miles ago. Used Welsh Poly Mounts and packers kit. Ride height is near 15 5/8" . Recent threads indicated the Toe Out can cause a similar problem and since Camber is non adjustable (?) what does this indicate? Forgive me if more than 2 pics

 

Since your ride height is with tolerance my bet would be excessive toe.

Can you take a pic from the front of the car showing both wheels so we can a look at the angle? It should be pretty obvious.

 

My bet is also on your toe being out of spec....

 

toed out a lot, you would have to be more than -2* or more camber to even start inducing that much inner tire wear.

 

Thanks for replies and info. I tried to get pics of both wheels but too low and dark in Garage. Now to find a Tech who has ability to do this correctly. The Specs listed for ROW F/E is Positive Toe of (.08* to .42*). Any suggestion of where in this range to finalize the Toe In?

 

Hey kstevusa, where do you go to see the pics? I cannot find the attachments. I also had severe inner tire wear with a camber that was off, ride height was over 1" too low. I thought for sure it was a camber issue but had the toe adjusted and it totally fixed the inner tire wear. I went through a pair of front tires in only 2-3,000 miles when I first got the car and before I had fixed the toe.

 

Thanks for previous posts. Had the alignment checked and the Front Camber was off. Left Front was -1.3 degrees and RF was -1.3 degrees. Toe was +.13 degrees LF and +.14 degrees RF. Looks like the springs have sagged. The Welsh Poly upper mounts and 25K mile shocks should be OK. The ride height is below 15.5" I think. Difficult to get detailed measurement from the arch to hub center line to be exact. Does anyone have a quality A/M supplier of springs or should I order OEM for my Coupe? Do Not Want to Lower it. Would consider RJ237 suggestion of a 3/8" spacer though.

 

that camber wont do that. I have had many cars over the years with even more that don't wear the inside. Did they check deflection while on the machine while pushing out evenly on both front inside edges of the tires?

 

I wish I could recall who to thank for posting this relatively recently. Do note the variance specs listed. As I recall a bit lower than 15.5 inch front height is within the specs.

###edit: I should read my own images. Thanks go to Rothwell.

I did not physically SEE them spread and check the range of movement, but asked them to do the procedure. The wear shown is after a 23K run on this set of front tires. The Shims were installed in the correct position when the new shocks were installed. Used that particular article to determine location of shims. Fortunately the shop advised No Charge since they made no adjustment. I will attempt to secure a accurate measurement from hub center line to the wheel arch and then continue. Thanks!

 

Handmade by my mechanic. combined with the coilover kit you get perfect adjustment!

 

Are the inner tie rods the originals?

 

Yes the I & O are original since I have not changed them. They have to lost motion and appear to be good.

 

The inner and outer tie rods are where you get the most stacked tolerances which is why i recommended you have them check deflection on the alignment machine and preferrably while you watch. Reason being, they may not understand what you were talking about, and 2 "oh great another guy reading forums trying to tell us what to do!"
as a tech im always asking myself why something happens, and how can i diagnose it or fix it and do it faster next time
thats how i learned about why merecedes wants you to use a pressor bar when doing an alignment. It works on all cars and is beneficial for more accurate alignments on "the car" youre working on. Especially revealing on older cars that have increased tolerances vs new tight suspension

 

Update with ride height info. Used a laser level on my trolley jack to mark center of hub and determined the following: L.F. was 14 3/4" Ctr to Wheel Arch. R.F. was 15" same method. I have the Welsh Poly mounts and replacement shocks (25K) ago. Looks like my springs have SAGGED. Appears the springs are only variable. The mounts show no deformation or deterioration. Do not think a set of spacers would correct the springs drooping. Time to "Bite the Bullet"

 

Where can they be purchased? I think they are what I need to get my camber back to spec. I did everything else except replace the springs.
