Left Rear Wheel Tilts a Bit
Just returned from a 70 mph drive and noticed no unusual noise, my good
neighbor, noticed the left rear wheel is tilted inward, in other words the top of the wheel is tilted inward as the bottom is tilted outward by a couple of degrees. I jacked the car up and the wheel has no movement when I kicked the top or sides, taking a quick peek underneath, it's raining in Boston, saw no abnormals .....had the rear wheel bearings replaced about 6 months ago and just on big pot holes or angle approaches to the driveway, would hear a slight tension sound coming from the rear ......Maybe it finally broke ... Plan on taking a 400 mile trip this Friday, wear the tire a bit, but am concern about causing additional sever damage... minor damage will not bother me ....TIA Bill 1981 300 TD

Couldn't that just be from the rear end of your car riding low or sagging?

I agree. Take a look at the opposite wheel. They are probably similar.
The lower the vehicle rides in the back, the higher the negative camber. Nothing much you can do about it unless you get the back end higher via the use of new suspension components and/or taller springs.

Take a closer look.....
Some years ago I had an '82 240D......it somehow managed to develop a crack in the ...I can't remember the exact name of the part, But....the big "V" shaped steel piece that the Axel Shaft assembly passes thru.....the crack appeared just under and a bit inboard of where the wheel bearing rests....caused the rear wheel to can't inward at the top....just as you describe......
Please check closely, this could become dangerous.....and a real pain of a problem on a 400 mile trip..... Luck to ya.... SB

The right wheel is vertical and shows no sign of tilting ....
You do remind me when I had about 800 lbs in the rear of my wagon, and the rear covers the top of the wheels a lot ...but can not recall any tilting the height difference today of the two rear wheels are about 4 inches or so .... so the left rear wheel is sagging ..... Sounds like no big problem to drive 400 miles and avoid pot hoes and the like ....TIA Bill 1981 300 TD

Sounds like a failed hydropneumatic shock on that side??

Now that I think about it, it could also be a failed line to that shock, or perhaps low fluid or a failed pump or maybe a failed level detector switch. In any case, it could lead to some dangerous handling characteristics under some circumstances so I'd be a little reluctant to do a long drive without troubleshooting it.
The simplest method I have for testing the hydropneumatic shock system is to start the car while sitting in the driver's seat with one foot on the ground. After the engine starts, I can feel the car rise as the shocks are activated and then settle back down to the proper level. You can also use the rear view mirror and get the back of the car and a distant object in view and watch the rear rise as the system is activated. I've never done a comparison side to side.

So, what is the fair cost to replace the Hydropneumatic shock???? Too big of a job at this time of the year for me ....I thought it might be the sub frame or the Hydro shock .... TIA

No, that is severe ..... never drive that car better to be towed to where you want to go.... mine is about 3/4 less than the photo... all tire surface is on the ground ...

Fastlane has the shock for $375. Labor shouldn't be more than a couple of hours I imagine. I'd do some investigating on fluid level and general function before asking for a shock replacement. I think it might also be a failed nitrogen sphere accumulator on that side. Does that side have any evidence of shock absorbing capacity and is there any evidence of a leak? Accumulator is only about $110.

I checked the fluid level,leaks, and the like looks fine....The nitrogen sphere accumulator on both sides have never been replaced since I've owned the car for 15 years .... What do there sphere do ?
Hit a bump in the road on the left tire and the rear followed about the same, no noticeable difference. I like to ask about cost for a repair so when I go to the garage, I am prepared somewhat ..... Bill 1981 300 TD

All I can say is, check the rear control arm carefully. I had mine rust thru and crack. Rust started from the bottom 2/3 turn of the spring breaking. Wheel developed lot of negative camber. I'll see if I can find the pictures I took.
