Hello Jim,
Have you refitted the bush housing in exactly the right position? Did you measure the distance from the rear end of the housing to the end of the original suspension arm and transfer it to the new arm? There's a horizontal line cast into the end of the arm which should be parallel to the base of the bush housing. This confirms the correct rotational position. If you're still stuck, then extract the ARB saddle clamp bolts and move the bar forwards to make the job much easier. I recommend this anyway because the bush bolts' specified torque is 150 Nm. This job is not easy by any means so your frustration is normal. As you say, leave it now until tomorrow. A new dawn has got me out of trouble many times! Simon

The arm is under a part rotation in situ so the bracket needs to be twisted slightly to line up the bolts. I used mole grips gripped and locked on the webs of the bracket to apply the bit of twist. Mole grips in one hand and bolt in the other, turn bolt anti clock until aligned then feel it in. Don't spanner it until it's well started.

Thanks to all who have replied particularly to Simon for the well established advice to sleep on it.
The bush is aligned correctly on the arm. The threads in the arm and on the bolts are perfect they thread easily. The difficulty is in aligning the bush holder to allow the bolts to fall correctly into the subframe socket. With the hub on and the outer balljoint disconnected I can almost get there, but there is about 10 degrees off vertical that I can't correct with the hub in place because the hub restricts movement of the outer wishbone. I can correct this with an f clamp on the bush holder but cannot even then get the bolts to thread. With the outer balljoint in place and jacking up the hub to take weight of the car things are worse because there is no movement left in the wishbone - attempt to correct the 10 degrees broke my clamp! I realise this is a problem that others have not seen or have solved with one of the methods above but they are not working for me. So I am going to take the hub off the strut to give more room to adjust the wishbone and align the bush holder correctly. Reluctant to drop the subframe unless no other way. I imagine this would be easier with car on ramps and 2 strong mechanics but can't help cursing the engineer who thought this up. Have worked on Rover p5 and p4 with their massive suspension components and seen nothing as frustrating as this. |

Something is amiss here, I have done these in 45 mins per side on my driveway! They shouldn’t give you this much grief?

Agreed Trikey
At least 6 hours so far trying to get the bolts to thread - albeit not all in one sitting. Appear to perfectly aligned but just won't thread. I raised the thread in case I was missing something but I don't think so. Thank you! |

Another 2 hours on this today and no closer to fixing. With hub off got a bit more movement in wishbone to align bush holder almost perfectly, but bolts will still not thread.
So tried Trikey's method reassembled hub, attached lower balljoint and jacked up hub. The bush holder is firmly wedged against body by this manoeuvre and there is no way the bolts are going to get anywhere near subframe. When I see perfectly good cars in the scrapyard I often wonder how that happened. Sadly I have reached that point with this. The car cannot be driven at present and I don't see a way out as I have run out of time. This was supposed to be the easy part of the MOT fix. |

Things to check:-
1. The bush mounting brackets are handed (LH and RH). 2. Did you mark the relative positions of the rubber and the arm? (position along the length of the arm and position of threepeny bit shaped bush on the arm) You could be out on those? 3. Did you check the old against the new mounting and bush for similarity?
