The pinch bolt goes thru a tab on the strut itself, so even with the head snapped off the remains of the bolt are probably holding things together. When I went thru this, it wasn't due to over tightening on the install as much as it was due to the threads rusting solid. You are probably going to have to very very carefully drill the bolt out. Not a fun job![]()

Drilling out - ah nuts...
Thanks for the quick reply. -

It is corrosion at the root of it all. The pinch design allows plenty of crud to backfill in the passage and corrode over time.
I have the LH strut hanging free after hours of difficulties. Had to drill both sides of the broken fastener and sawzall on both sides of the pinch zone. What a pita.
I am off to get more drill bits, sawz-all blades and propane (for garage heat) so I can have a go at the RH side tomorrow...since it is as likely to break as not.
Good thing this car is so fun to drive! -
Please get and use some anti-seize when putting it back together. Save a lot of problems next time.

Plasma cutter time.

papa-j Active MemberLifetime Supporter
yeah, more tools!
No plasma cutter, but now I have a gift idea :biggrin5:
As far as never-sneeze goes, totally agree. I always use it. Living with Minnesota weather and salted roads makes it a must. All my underside Previa fasteners come off easy because of it (after their first time).
This yucko task is gratus the handi-work of original owner/mechanic coupled with my ignorance of the designer's optimization "choice" (drip path into a blind hole on exposed suspension). Live and learn. -
Have you tried the CRC freeze off penetrant, I've had some success with it before?

I have not tried CRC freeze off. I am a PB Blaster zealot. I will look at adding the freeze off to the arsenal tomorrow. Thanks for the tip.

Welcome and good luck!

The right hand side has released without breaking the bolt! Repeated cycles of MAP torch, Impact wrench in both directions and PB blaster did the trick. Now on to finishing the LH mess and do the mushroom smackdown + camber plates as originally planned.
Thanks for the support folks. Hopefully no more unplanned work on this small project. -

Good job! Now you have to post pictures or it did not happen. Hahahaha

A pic...attached is a shot of the mounts that were in there. Not flat at all :nonod:.... I flattened the towers successfully today which feels like progress.
I also got the RH stuff all together (yes, with never seize). Just need to torque to spec. It's satisfying to get that side in good shape.
The LH carrier has me vexed. I guess I will need to pull it and buy a replacement or have a machine shop work it (or else throw the thing in the lake).
The drilling won't go through :confused5:. Probably less than 1/4" remaining but no further progress is being made except adding to the collection of dead bits (amateur at the helm) Pretty sure there is a piece of cobalt drill bit buried in the center which is stopping my progress from both sides. So close...
Oh well, progress is being made. Little by little, and bit by bit <ha ha>Attached Files:

something also to consider and ive done this before myself and that is putting a light coat of anti-seize on the bottom of the strut around where there is metal-to-metal contact...keeps the crap out and provides a barrier...

Picked up a replacement carrier today and hope to have time after work this week to finish the job.
