Wife said she was hearing a clunking noise on right rear when turning right only.

Went out and took a look and saw what I was hoping NOT to see

I was aware that there was a small amount of rust on the mount but it appeared to be an amount that wouldn't be an issue for quite a while.

I was planning on replacing the trailing arm in a couple months anyway. I even bought a used one last year in preparation. I'll go ahead and have new 420SEL springs installed at the same time since there's a bit of labor overlap when doing both.

...would also explain why the back end felt squirmy on the hwy last night on my trip back from N.C :p

ck42, great pix, question, what does the writing on the bolt say, and what do the small triangles mean, anybody know???? steve

A little welding and grinding could fix that. LOL

Wow, looks like some of my parts cars.

No idea. Only able to see the letters after taking the pictures. Just stuck the camera under there and fired away.

Actually it kinda looks like pot-hole damage combined with weak shock. Suspension compresses to max and beyond very quickly and worn shock just makes it worse. Winds up driving shock thru mounting point. Friends RV cracked major wields on rear suspension (like on a VW bus) when he caught a big pot-hole in Chicago. Took about a month for the rest of the welds to break and the RV sorta lowered itself till the crossmember raised up and met the glass body.

It probably didn't help that we had the trunk loaded down on the trip. Can't recall any big pot holes. But, I figure that:

Sagging springs + aging shocks + loaded trunk + rusting mount = asking for trouble.

I have an old, faint memory of such numbers referring to the degree to which subject bolt is 'hardened'.

I think the writing on the bolt is the manufacturer Verbus, I've seen their bolts on other places on the car. I can't read the number but its probably a grade stamp.
