Some are a battle to free off, others just simply drop out with ease. May I suggest applying a jack under the ball joint and raising it slowly, this will relax the joint and the securing pinch bolt, apply some releasing agent and leave for a while. The other thing to also try is to steer the wheel to apply the pressure on the joint pin into a different zone of its position, followed by a few generous whacks with a decent hammer will see this yield eventually.
This problem is usually caused by repairers re-using the old pinch bolt and doing it up beyond its recommended torque. This has a number of effects, 1 the pinch bold shrinks at the shank that acts on the ball joint as the bolt stretches. This in-turn makes the joint clatter like hell no matter how tight you do the nut and bolt. 2 The hub where the ball joint enters the pinch zone has become deformed and too close together not allowing the joint to pass through it. (Once this has happened, it is unlikely to rescue any of the components affected by johnny big-boy's skillless operations. If you still have problems, you will need to spread the jaws of the hub carrier to allow the joint to free away from the hub, but remember the likelyhood of it going back together properly and lasting any time is unlikely. Also the use of the proper nut and bolt is essential as it the correct torque setting which is far from tight tight in reality. Hope this is of some help. Good luck. |

I did try it a bit but as I had read somewhere that this shouldn't be done I was probably too gentle and it may have had no affect. Now I'm in a different position (getting to the end of my tether!) I may be a bit bolder with this idea. Thanks for the suggestion.

What about an sds hammer drill set on just hammer function.hopefully the vibration should free it.

Thanks to everyone's suggestions I finally got the pinch bolt out this morning. Think it was a combination of opening up the clamp with a cold chisel and also putting the trolley jack under the clamp to ease the joint a bit. It had also been soaking in releasing fluid overnight which may have helped.
But, Ive now hit my next problem. The lower ball joint is fully released and out of the clamp ok and I've removed the nut from the other joint half way along the arm but I can't get the threaded stud up out of the hole in the sub frame (hope that is clear?). I have the trolley jack under the threaded stud and have raised the car on it so it has the whole weight of the car pushing on it but it still won't move. I've just put a load of releasing fluid on it and will leave while I have lunch but can someone tell me if I am doing something wrong? I may be making it a bit difficult for myself as I an trying to get the arm off without removing the rear bush as I've read on here that it is a real PITA to get to the bolts. Is it possible to leave the bush in place and still get the arm off?? |

HI Roy. I would say you fighting a losing battle trying to remove the front lower wishbone arm with out removing the bush /bolts first. Usually it is best to remove the rear bush bolts, then the ball joint bolt, pop that out, then the centre taper out of the sub frame.

I have decided to bite the bullet and get a new bush. I know that you have adapted some aircraft spanners to get to the bolts but do you know what other tools I could use? |
