Rear shocks. Hmm

congo181 · Nov 1, 2021

These are going to be tricky to get off I reckon.
It’s 1987 and they’re bound to be original.
Any top tips for getting that bottom nut off? The shock is just spinning on the knackered rubber bush. It’s soaking in PB Blaster tonight but…. Can’t really heat it much obviously.
Just bite the bullet and put new shocks on? What dya reckon?

Catch the shock with a chain filter wrench then a six sided socket

I’ve got a leather strap one but not a chain one. I’ll give it a go.
It’s also 3/4” not 19mm so I need to get a long 6 sided 3/4” socket. Blooming things.

+1 for the above, thats how I did it.
Or you could just disc cut the nut off and pull the shock up through

Even a small stilson should catch it as long as the teeth are good

Run grinder disc through above the bracket. Gravity will take care of the nut assembly

New shocks....obviously

If you use a compact driver it will spin it straight off, I had the same problem till I got hold of one myself

I’ve got a dewalt impact I use for woodworking but it’s not chunky enough to loosen anything really.
What’s a decent entry level one? I was looking at the Milwaukee brand.

Milwaukee fuel stuff is very good, but for a good brand at a cheaper price I went for a dewalt 899 model it has sufficient power to undo anything I have found on the 90.

Most of them of decent torque are fairly large size, I would recommend getting your hands on a few and seeing which ones feel comfortable and you can see you willl use in the spaces you have.

Plus if you are already using a branded ( mlwaukee, dewalt etc) battery system then getting one that uses the same batteries is a good idea as you can just get the body itself.

Cheers

The one I used was a makita took it off no problem!

I can vouch for the Milwaukee fuel impact wrench it’s astonishing. I used it to dismantle my rusty Sankey by just twisting the heads off everything lol

it’s also awesome for undoing crackshaft pulley bolts when doing timing belts - it’s the only impact gun that seems to be able to - my Clarke and my makita both failed

I'd run a wire wheel in a drill over the exposed threads and then (as everyone has said) you need to grab the shock (at the bottom to stop it turning, its solid there, 2" up and it;'s just a thin tube full of oil). An impact wrench works better than a spanner. Heat will also help, a plumbers gas torch on the nut, failing that @Beneagles method will work ....

Well I got them off.
One pin is decidedly ’jaunty’.

Did you need an impact driver?

I soaked them overnight with PB blaster which is pretty good, then I used a breaker bar with a pair of gas-grips to get them moving.
After that my little dewalt impact could spin them off.

Nice one pleased you sorted it, I had to change my bump stops last week, even impact driver didn’t work, and trying to hold a poxy 9m spanner on the top is just a joke so had to grind them off in the end!

Sometimes the grinder is the best spanner in the box. I ground of all the bolts holding the tub and the screws in the floor panels. Didn’t even bother trying.
Mechanically the dampers are pretty far gone. There’s loads of pitting and the bent pin isn’t great and the bottom bushes are toast. May have to get some new ones.
