has anyone else ever experienced this or seen this happen on an f,J, or M body car?

I heard a crack sound right before I pulled into my parking spot at work a few days ago.. I knew something broke but couldnt tell what.

I nursed it home to find the steering really wacked and this:

Wow. Is that the upper control arm mount? Looks like someone adjusting the upper control arm torqued that bolt way beyond the spec and cracked the mount. This lead to flex and fatigue and eventually breaking.

At least it looks like it is a bolt-on part.

That rust doesn't look to helpful either.

I would recommend getting the suspension out of a slant six wagon (F/M body) , bead blasting it, repainting it, ad reinforcing it before installing it in your car.

Well the part is fixed.. I replace it with another one.. I specifically asked for more positive caster when I got the car aligned.. that would be my guess on the reason why The bolt was so far to the extreme end of the adjustment. Maybe I will ask for less this time around.

That was a known failure point on the F/M/J cars. Cop cars got a reinforcement in that area. If someone (like Dan) has the parts book with the M-body police car stuff it should be shown.

Well it's Been a year since the top of this post, but I had trashed the original broken Piece you see at the Top of the post.


My replacement did the same thing but Worse - Both parts completley broke off Before the big storm Hit here in PA.

So this is the end result. I did not have another right side piece to throw on So I had to weld and beef up the broken one.





Also added a bit more material to connect the Extended Parts where the Cracks seem to start.

I gotta get some more of these to keep in stock and just beef them up with the welder before installing.

I think a 2nd plate from underneath, the whole length (front to back as mounted in the car) and at least 1" past the end of the slots ("in-out" direction as placed on the car) and then cut the slots in the reinforcement plate to match the ones in the busted place would help distribute the load a bit. Trace pattern, cut out and weld in fom underside. That's one of those things I've heard of but til now never seen. I have those plates all blasted and painted (POR 15) for mine but after seeing yours I might have to beef mine up before reassembly. Wow!

The reinforcements I have seen, look like the "clips" they used to sell that you slide onto a side post battery for better access when "jumping" only a larger version. I think this was the "recall fix" for these cars.

That'll teach ya to drive an F body...

Well This is on a daily driver that sees plenty of hard driving, and many salty slushy hills here in western PA. Which means potholes too.

Don, I think if you are doing a summer diver / Show car you should be fine, but with the salt bath these start to go south quick. Your plate reinforcement Idea sounds good too. I am going to stop over at dippy .org and the f body forum and see what solutions they have too.

I got it aligned today cause school/ work was cancelled for me so that's good. I Plan to take that car to the Banquet in TN.

I'm working on an F body myself.... alot less common than the GM version for sure. but I've had others as well as several M bodies (Diplomats etc) and never had one do that on me. (but again I've "heard" of it) I believe that just like the rotten fender issue it's an "early model" issue.

Check with Fbody Deconstructor Jim, on a set of rust free ones from out in the Desert.

Cool Don,


Thnaks!

Yep Lou plan to have it with all it's road grime and glorious pounds of rust protection.

I think the F-body website is gone

nope. they added another name and there was talk of dropping the original. I still have a "cookie" in mine so I get right to it.
In fact I have been swapping PM's with the site "owner" over a reference I made to a post on another site and got deleted; someone was looking for parts and I saw someone selling those very parts on another site which the F body site owner "doesn't like" (not this one)
the references here haven't been touched. (it's the "old Hippie" site he don't like)
