hello my alfa 147 (51 plate) has failed mot on upper suspension arm bush. i have the part coming in the post i just want to know how easy is it to do? do i have to remove the strut? please anyone can u help?
You will need to drop the strut to get the long bolt out of the upper arm. This is what worked best for me:
release and remove the long lower bolt from the damper fork attaching it to the lower arm.
release the ARB droplink (just one of its bolts, you don't need to remove it
release and remove the bolt holding the damper in the fork and split them
let the fork rest on the lower arm or remove it completely - this will make you a lot of space under the damper
split the upper arm balljoint holding it to the wheel hub strut
release the 4 bolts in engine bay on top of the suspension turret - this will allow you to drop the upper support/upper arm/damper/spring assembly few inches lower
remove the upper arm bolt, replace the arm and put all back together
This is what I used for suspension install, maybe you don't need to do all of it for the upper arm, maybe it would be enough to disconnect the ARB, lower fork bolt, split the upper arm ball joint and release the 4 bolts in engine bay and by this you might be able to drop the suspension strut low enough to take out the bolt of upper arm...
The job is fairly easy, to only problem are stuck and rusted bolts
Don't forget to to the tracking after, its really a must. Once I forgot it and ruined the tyres in 2 months as the tracking was almost -3mm toe-in after upper arm change...
The anti roll bar drop links are pigs as the allen keys bolts locating them round off easily. I would recommend having a spare to hand just in case. This way if it does stick you do not have to worry about destroying it to remove it.
When you drop the "strut" down a couple of inches you can then lift off the holder for the top arm from the top of the strut and undo the bolt for the top arm off the car.
