Soild Bushings Bolts

[Bruceynz]

Hi Guys,

I have managed to get 3 of the 4 big bolts that go through the subframe and isolators, I have hit a snag the 4th bolt is real hard to turn, I don't know what sort of nut is inside the frame rail, feels like some square that sits in there. I have tried to squirt CRC 5.56 down there through a hole in the chassis. Can the nut inside the rail the big bolt screws into spin in there or is it to big, if it screws around I am in a bit of bother.

Thanks
Bruce

It is welded. Soak the living crap out of it with penetrating oil. You may have to loosen a little, then tighten back up, spray it, an repeat until it comes out. If the nut breaks loose it has to be welded back in place.

 

[Bruceynz]

thats my worry! if it breaks!

 

[80mirada]

What are you using to loosen it? An impact on a large ratchet, etc?

 

[Bruceynz]

a power bar about 15inches long and its hard, the others all cracked and with in a few turns could undo with my fingers

I would try a 1/2" air operated impact. It will hammer it while is turns it.

 

[Bruceynz]

oh I can turn it alright but boy its stiff! anyone know whats in there, is it a nut on a plate?

What do you have supporting the K-frame. It might be binding that last one. I assume you're doing this with the engine in?

 

[80mirada]

It is a nut welded to the inner reinforcement that runs parallel with the top and bottom of the rail. Penetrating oil and an Impact would be your best friends for this job. If the nut had broke loose it would turn easily.

big jack checked it was not loading the bolt up

 

[Bruceynz]

I have the body supported under the jacking points with some wooden blocks and under the K member I have my high lift Jack

You probably have some corrosion in that one bolt. Do you have access to an Impact, preferably an air one?

 

[Bruceynz]

It finally came out, took about an hour in total, CRC it, leave it, undo it do it up a bit, CRC it, you guys know the drill, 30+ years of being in the same place = I dont want to move

I did all four on a Volare like that one time

 

[Bruceynz]

the steering gear seems to be a problem, do you need to drop the steering box connection?

 

[80mirada]

You could remove the rag joint bolts, if the rag joint gets out of alignment it can be a bitch to get it back together.

lets hope I haven't stuffed it then I have jacked the car back up again and bolted things up hmmmm
