R33 GTST coilover removal

[BlackLine33]

Changing the old coilovers in the Skyline for brand new ones.

Front driver was rusted on at the bottom where the 17mm nut is. I used a ball joint splitter on it which got the coilover out but it's left the inner metal ring with the rubber on it. I've used Wd40 Penetrant, shock treatment with a hammer, and heated it up with a heat gun but it won't budge.

Any suggestions?

Have a couple of pics attached for reference.

Cheers

get it nice and warm with a blow torch (no idea what a heat gun can do, but not enough), the get a pry bar behind it and shock it loose. If you need to get a grip on the bush a big pair of vice grips would help

Well, it's f**ked, so you might as well just touch it up with the Dremel or a hacksaw to make it easier to release its grip.

What Dremel model would you use?

Doesn't matter. I have one of the original quite small ones. The small friction cutting discs that fly to pieces and take out your eye work, as do the thicker fibre reinforced ones. The thinner grinding wheels work. Steel cutting burrs work. Any of the larger Dremels that take bigger discs/burrs are also good. A 4" angle grinder will do the job, if used very discretely. A reciprocating cutter can also work. I just use the word Dremel to indicate anything that can cut/remove metal at a smaller scale.

Tried the Dremel but might’ve made it worse and cutting more than i should. Not sure what it's going to take to get it off. Trying to soak it in vinegar if that will even do anything.

looks like you haven't hit the thread underneath, so no issue there.

you should still try to get a pry bar behind it to shock it off, and heat will help. You only need to break the seal then it will come out reasonably easy

I'll try a blow torch and pry bar next. What do you mean by shock it off?

[Duncan]

I mean, grab a pry bar or even just the biggest screwdriver you have that you don't care too much about, lever it between the bush and something solid, then give the end of the bar a firm push (perhaps even a whack with a hammer)

Got the blow torch and heated it up well. Smashed it with a hammer to loosen it then managed to get it out with pliers and a vice grip.
