lower ball joint - doing the nut up tight
ditchlewis - 2/5/09 at 06:28 PM

just been setting the front suspension up.

the bottom ball joint has nylock nut on it and i discovered than once i moved the wing stay the bolt was not as tight as i would like it, but the nut just turns the ball joint.

how do you stop the joint turning whilst you do the nut up.

I put a jack under the ball joint

force the wishbones together, mine are a bit different to yours, but i stood on the top wishbone, if you've got a nylon ratched strap or something, wrap it round the wishbones to pull them together

i tried standing on the top wishbone, but then i fell off when i tried to tighten the bolt

i will get one of the kids (they are 6'4" to stand on the top whilst i tighten the bolt

thanks lads

my bottom ball joints work differently to yours though, the nut on my uprights is on the bottom of the wishbone (the stud enters from the top) so it may not work for you.

try putting something like a big block of wood under the bottom wishbone with the wheel off the grond, and get someone to sit on the wheel

ok

my stud enters from the bottom.

i will try the block under the wish bone and the person on the wheel

glad i've got big kids, bit you should see how much they eat.

Nut runner?

I'd second putting a jack under the wishbone. Forces the swivel into the taper and allows maximum nut tightening

You have got your wishbones the right way round? Not even sure it's possible to get then wrong but if the taper is the wrong way it'll never tighten properly.

This only works on suspension setups where the spring/damper is connected to either the upright (e.g. McPherson) or upper wishbone. On a Locost a jack under the lower wishbone doesn't increase the pressure on the ball joint taper whatsoever, unless you also get someone to sit on top of the tyre!

A ratchet strap carefully applied between the wishbones is the easiest method IMO. Get the strap as close to the ball joints as possible to maximise pressure on the joints and minimise the chances of bending anything.
