Help!! Stuck Bolt.

Sep 24, 2003 4 Replies

While swapping the rear leaf springs on my SIII last night, I encountered a bolt that won't come out. It's the one that secures the front of the driver's side spring to the chassis, and it seems to be stuck in the bushing. I've tried liberal amounts of WD40, belting it with a hammer, and also using a socket with an extension bar to try to work it loose, all with no luck whatsoever. Any suggestions would be much appreciated, especially since I successfully did the other side the night before and it's sitting about 4" higher (the springs were seriously knackered).



Not sure about using heat, on account of the proximity to the (diesel) fuel tank.

Set fire to the rubber in the bush, burn it out and then the centre bit, complete with bolt, will drop out. Remove outer bush casing and fit a new bush

If you're that worried about the fuel tank, take it off

Alex, I have used the following technique successfully although it takes time and is not without it's risks.

Use an angle grinder to get rid of both ends of the bolt, so that you are just looking at a rubber bush with a metal core. Next, find a hole saw to fit your electric drill, with a diameter such that the hole saw will cut into the rubber, the centre of the rubber and the remains of the bolt progressively sliding into the cylinder of the hole saw. Run the drill slowly and persevere; approach the problem from both ends of the bolt. Eventually the rubber core with the remains of the bolt should fall out. You can then use a hack saw to cut through the outer sleeving of the bush and knock it out of the hole in the chassis.

Good luck.

Don't know if it helps, but I had the same problem with my front ones last week when I changed them. The last bolt of the whole job to try and it was the only one that stuck!!

I (after ages with an angle grinder) finally found that the bolt had seized in the shackle, at the head of the bolt end. I used a drill with a 14mm metal drill bit to carefully drill another hole through the shackle, where the old one had been.

Well, thanks all for the feedback. I had a mate from our club around last night, and after a variety of creative but ultimately futile ideas, we resorted to the angle grinder - cut a load of the end of the spring away, then got through the bush & bolt just inboard of the chassis hanger, then cut off the bolt head and knocked it through. The bolt was completely corroded to the inner metal sleeve of the bush. We've fitted the replacement spring, using a bit of threaded bar to hold everything in place while a replacement nut & bolt comes from Paddocks.
