Did you change the wishbones and the bushes (all 4 parts shown here) or just the wishbones? |
Hi all
Just about to do this job. With this method, do you need to break the subframe balljoint before detaching the bush and the lower strut balljoint? thanks Jim |

Thanks for that - so to confirm "hammer head" method steps in order will be: release bush mount at rear. loosen subframe balljoint nut. Jack up under strut lower balljoint to create space. place hammer head as fulcrum in space created. Let jack down to break subframe balljoint. Undo lower pinch bolt and balljoint. Have I got that right?

i just cracked the lower joint first then nipped it back up when i did mine .
i havedone 5 now. i dont think it makes much difference apart from recoil on the pin and swivel hub being a damage possibility albeit slight. the subframe balljoint only needs upwards movement of a few thou so is not impeded for upwards movement anyway. another point to mention is that the rear bush whilst still bolted also absorbs the shock effect from hammer blows due to the rubber bushing insert .just remove the bolts anyway. it also depends how long the bush has been in and how rust welded the joint has become. i have never bought into the idea of raising and dropping the car down quickly on to a solid support to release method. for me it never worked because if you look at the angle of the subframe joint through the subframe its not vertical and by dropping it onto a support below does nothing . you may as well hit the pin sideways because it achieves absolutely nothing . dont expect the subframe joint to pop out immediately whilst under spring pressure everytime. on two of mine all that was needed was a couple of taps whilst it was under pressure from the spring and out they popped. key to it is remove bolts on rear bush first this will give more pressure to the spring. good luck. |

Thanks all. It's proving a challenge. No movement with the fulcrum technique and lump hammer. Have applied heat to pin end and even managed to get a chain round the subframe to use 2.5 ton trolley jack to apply 2.5 tons of pressure. Nothing! Fortunately not in a hurry. Will get bigger lump hammer.

The higher the car from the ground the better the swing with the hammer , A Heavier hammer performs better as it is less likely to bounce and transfer's more energy to the item been hit . A few big hits more effective than a lot of small taps , If your replacing the arm a bit of bruising isn't a problem anyway If you keep assaulting it the taper will eventually give , and then you be left thinking what took all the effort :eek: Failing that others have had success with a puller , but up to now and I have done a few never had to resort to more than the hammer The arm I am changing has slight outer ball joint play but been the original arm is 17 years old so has given good service |
