Hey all.. I'm trying to undo the 2 rear lower wish bone bolts on a mk1. It's the bolt by the hub. They are stuck solid. I have oiled the hell out of them beat the sh*t out of one of them to the point where I've ruined the bolt.. is it a case of just cutting them out. I heard they can be a bast**d.

Have you tried heating them? And for the ruined bolt it's get a vice grips with decent teeth into it to try turn it...then heat and try turn and keep repeating

Haven't tried heat.. I don't have a blowtorch thingy. I'll try a heat gun tomorrow.. cheers

Heatgun wont get hot enough. You can pick up gas powered blowtorches for handy money

Well lads. Tried it with 2 heat guns today and got it out. The bolt is fubar but I can just replace that. I'll try the same on the other one tomorrow. Jesus I'm wreaked after it..

Hello Ray
I think the biggest problem is that they come through the bottom of the stub axle and are exposed to all the shit from the road , in the past I've cleaned as much of the rust from the exposed portion of the bolt as possible using hammer and chisel , rotating the bolt using a long 600 mm breaker bar( my very BEST friend ) then cleaning more , I would also recommand my old friend worth rust off , great stuff I think . The heat will work but you need a proper blow touch , something like what the Plummer uses and be carful not to melt the bush .
Och the joys of restoration !

Thanks for the advise Brian.. I did try scrapping some of that crap off.. I had a go at the second one yesterday but no joy. Gonna give it another go today and smack it with the big heavy hammer.

I had the same problem when I was doing my bushes last year it is a pig. lots of regular spraying didn't work hitting it didn't work. An impact driver didn't work. In the end it was a gas powered torch and a 4' scaffolding bar got it out.... for the record new bolts are £15 each from mazda, ask me how I know.....

Got the second bugger out... my new motto "hit it with the big hammer"

That's great news Ray
Make sure when your refitting the bolt to grease it and pack the exposed portion with grease as well , it helps keep the rust away .....big hammers , I live them !

Will do Brian.. just need to pick up a couple bolts now. that's the thing with big hammers. big damage
