steering knuckle

[Finnon]

The tsrm says to remove the steering knuckle i have to remove the upper control arm from where it bolts to the subframe and remove the lower ball joint from the bottom arm. then dissasemble on a bench. is this the easiest way? i have wd40/plus gas'd everything up that id need to undo if this was the case i just thought id check here to save myself any heartache/ unnesesary work.

also ive heard plus gas is a whole load better than wd40 so since im going to be droping the tank out to fix my leak can i buy plus gas in a spray can? the plus gas i used is like about 35-40 years old (my dad bought it when he was an apprentice mechanic lol)

cheers all

oh btw not sure if plus gas is available in the us. i cant find anything called pb blaster over here.

What are you trying to do.
It depends.

The screws are weird on it as they are pressure sensitive to tightening.

Simply put it needs compression on the bolt on the arm not to continue spinning if you are going to d/c it.
If you have a c-clamp you could pull it off at the knuckle.

the wheel bearing is knackered. i got a whole replacement knuckle as its gotta be easier to swap em over. (this all started by trying to replace the abs sensor.) so i was going to remove the whole lot inc the upper and lower b/j's and disconect everything on a work bench.

i figured it would be easier than trying to force the upper and lower arms out of the way enough to get the knuckle off

Well, I've pulled it off on the car and it's not a problem with the proper equipment. Out of the car is always easier if you're sure the other bearing is good I'd go ahead and swap them.

the replacement seems to have no play, the one currently on the car has extreme amounts of play. like i can hold the studs in my fingers and easily rock it side to side and up and down.

i guess a 17mm or maybe 19 socket for the track rod end and a 21 mm spanner for the upper and lower b/j's.

Honestly I don't remember.
That sounds about right though.

ahh well ill give it a whirl tomorrow, ill let the release oil work its magic over night.

 

[Finnon]

well i havent had a chance today, had to go and measure up a house for some architects drawings. place had a swiming pool and everything lol (fairly unusual in the uk)

still i bought a can of plus gas to help with the release oil i put on yesterday. hopefully it will sort the nuts out so they come of more easily

 

[Finnon]

its fitted. A passing friend saw me looking at it so pulled in to help me out. He works for the aa so is a fully qualified mechanic.

edit. the lower ball joint nut was a 22mm, the upper ball joint was a weird sized nut aswell. Is this usually the case?

 

[JustAnotherVictim]

I believe so.

ohh well ill know for next time. Theres a dodgy creak noise from the front suspension. But it has always done it and never failed an mot. guess ill change all the parts over gradually to fix it.
