Angry Battle of the Bolt (lower arm to trailing arm)

I'm having a major battle with the lower arm to trailing arm bolt (OSR) - I got it part way off then the nut refused to go any further due to rust on the thread. So I decided to attack the nut itself. This is the result after more than an hour with a nut splitter and an oscillating multi tool.



Would you believe it, the little swine still refuses to come off.



The nut splitter would have got it first time if it hadn't been for that pesky flange and the multi tool would certainly polish it off if it wasn't for the fact that all my metal-cutting blades are blunt.

Why has no-one come up with a way to protect the exposed ends of bolt threads.

Same old process, speed speed and some more speed, not many bother about how easy things can be made for next time it has to come off !
So many cannot even get wheel bolt torques correct, so we are all fighting the battles created for us.
I would soak EVERYTHING now in PlusGas, and leave it for time to work it's magic for when you return !

Hope things improve !

A dab of grease or wax once fitted would help.

Just what I did, after a wire brushing, using a breaker bar to tighten gently first, then loosen. An axle stand under each hub helped also. (Although a bit late for the op)

I gave it a lot of Plusgas after splitting the nut and it made no difference. The side of the thread nearest the camera (not visible in pics) is the problem.

A new metal-cutting blade is the answer - assuming I can stop the bolt rotating in the bush.

Chipping away the excess flaky rust with a chisel or such then a quick run over with a die nut before trying to back of the nut will clean the ends of the threads up nicely.

Upon reassembly a bit of grease on the thread then a little section of rubber hose would help stave of corrosion for a while longer.

I won the battle - will post a pic later. Hacksaw!

What about a good dose of Bilt Hamber Dynax UB or UC on the new nuts & bolts (and everything else underneath)?

That's a good idea. How did you seal the end up?


Meanwhile, here's the offending bolt/nut - it took me about 3 hours to get this one off. If I'd known how tough it was going to be I'd have hacksawed the exposed bit of thread off right at the start, then the nut has no rusted thread to complain about.

The heat shrink is 5ml longer than the thread, once heated squash shrink with some small pliers then trim the end if you need to.
