Did this last fall. If the tab holding the nut breaks you are SOL big time. I spent probably 4 hours snapping those nuts with a cold chisal and a 3 pound short handle sledge. Every one broke on me.


Their is no way to get a wrench in their. You simply beat the nut to death and it will crack eventually.

Start soaking with penetrant and keep it wet for as long a period as possible.
I have wedged a pry bar into the opening to assist the weld in counterholding the nut.
Again, soak, soak, soak.

Lol, doesnt sound promising!! I think i'll keep soaking them with some WD40 or similar, maybe wiggling the bolts from time to time to take it into the thread.

I could butcher a large spanner with my grinder, and make a 'special tool', but i'd still have to make the openings a bit bigger.

Surely they could have made this job a bit easier!

Also, we have used a pneumatic hammer/chisel to distort the weld nut before attempting to loosen it.
Best of fortune my Friend.

Squirt some PBlaster into the slots. I doubt if you will have a problem undoing the bolt.

I read about a product called Wurth Rost off Ice... Apparently it freezes whatever you spray it onto to -20'c which does similar to heating... cracking the rust locking the bolt to the nut, and its a penetrating fluid too... so maybe i'll see about ordering some up.

Well I havent gotten around to doing the guide rod mount yet, but I did change out my bottom ball joints this weekend. What a PITA that was. I changed the brake discs and pads at the same time, and even that was a nightmare. There just didnt seem to be enough room between the new pads for the new disc to fit in between!
It gave me the change to soak the subframe nuts with penetrating fluid though. Gave them many squirts throughout the day.
