Nuts

[Neil Clark]

The bottom nyloc nut securing one of the Koni's on the rear of my car seems to have stripped its thread, or the bolt thread has stripped, I can't tell yet.  Do I ned one of those nut cracker things or is there a trick to getting it to grip enough to come off?

[Colin Lindsay]

Don't damage the thread! The nut's a lot cheaper and will probably have to be cut off, if it won't unwind by itself. Try a screwdriver between those two washers as you unwind the nut, and lever the nut outwards as you do so, it may just force it off as it rotates or help it bite cleaner thread.

[Pete Lewis]

you could lever between shocker and upright to get some load on the nut whilst unscrewing 

if the thread as pulled  i reckon we die nut a metric thread to repair

Tried levering - will do so again but I'm so ham fisted.  I think I'll leave it until it's ready to go for it's MOT (paint shop says they are starting the bonnet but no idea when the body will be finished though) and get them to do that and check for my other bodges as part of a safety check ahead of the MOT.

Can I recommend you don't leave it.  Would be really easy to forget it, especially as it looks fine at a glance (but not something you want falling off!).

[poppyman]

You could cut the nut with a junior hacksaw, and then wedge a chisel in the cut to spread it and then it will fall off. Time consuming but will work.

Would an impact wrench work ?

No; it will just spin the nut around and maybe cause damage due to the speed. The nut needs to be unwound but also prised / pulled outwards on the remains of the threads. 

That's why I was suggesting a screwdriver in between those two washers; hammer it in if necessary to get it started but the outwards pressure may push the nut off the damaged section. A twisting motion of the screwdriver as you unwind the nut will also put outwards-pressure on it. The aim is to remove the nut but not damage anything else, as a replacement link costs quite a bit these days.

Yeah, that horrible moment you realise the tread on the upright is knackered and it's not a bolt you can replace!

[Pete Lewis]

but you can die it with an alternative ..mine was like that for 15 years and is still around as far as i know 

the nut only stops the shocker coming off its not taking much load

but only if you really have to...

you know you want to  !!!!!!!!

Is it the nut turning or the Bolt ?  An open end spanner will show you what's turning - just the nut or the nut and the bolt. 

If it's the nut then you have plenty of access to use a hacksaw a 45 degrees to the nut and to cut it part way down (to just before the stud's thread, so as to not damage it) And then a hammer and cold chisel into the cut,  to crack the nut open enough to work it off  ..so all in all just a few more minutes task.

I think it would be unlikely for that particular "bolt" to turn free, as it's a welded-in part of the upright. Hence the comments about not being cheap/easy to replace!

I usually resort to these... https://www.toolstation.com/nut-splitter-set/p80007?store=E1&utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gclid=Cj0KCQjwupD4BRD4ARIsABJMmZ9UL_4O-B8oq3XOLSoi9nNMU63WnZHiHKXuc8gL5QZakPYnWz0f_4QaAopAEALw_wcB

It's the nut turning.  But I have no idea of the condition of the thread underneath although the tiny bit I can see looks viable.  It's not loose laterally, as Pete says.  I might put this in the "waiting - too difficult" tray on my desk and ponder - and have another fiddle soon with the screw drivers and possibly my junior hacksaw.

[Colin Lindsay]

If the nut is turning, but not biting the threads then what's holding it on? Nowt. Pull or prise it straight off. If it's held on by some threads, then it needs to be prised to a spot where the threads will get a better bite. It's not a big job. Go remove it, young man, and get a large pat on the back from all of us when it's done.

[Peter Truman]

I wonder if a ball joint tapered breaker could exert enough pressure to push the Nut back to engage a thread.

Personally I’d use a used smaller dia Dremel cut off Disc to cut thro the nut As best I could The washers are replaceable.

Go on cut the nut off, you know you want to do it.

Once you have sorted it you will feel a sense of satisfaction.

If you want to replace the suspension arm, talk to Spitfire Graveyard.

That if you do not wish to recut the threads as Pete L suggested.

Haven't been called young for a while!  Peeing with rain here today and work is suddenly busy so it might be Friday earliest.
