Hello all,
As per the thread, keen to tackle replacing the rear trailing arm bushes (triangular ones fixed to the chassis) and the a-frame ball joint (full assembly). In either/both instances, does the rear axle need to be jacked up, does the rear axle need to be hanging (with the chassis jacked up), or can the whole thing remain on the ground? If either do need to be lifted, can you please tell me which one and why? Of the latter, so I can understand why and know what I’m looking for. Ta  Monsieur Le Grenadier

I would support the vehicle with axle stands under the chassis, you can then use the jack to maneuver the axle if necessary.
I'd do both arms at the same time, then the ball joint. |

When i did my A frame ball joint i jacked the tow bar and body away from the axle so i had a bit more room in there to get to the nut. 110 Td5 Ex Utilities slowly converting into a pop top camper one day

I might be the only one but I had mine done for me, on a lift. It was a job I just didn’t fancy tackling. No Guts, No Glory.

Easy job 👍🏻
Jack up via axle so wheels off the ground, support the body with axle stands on the chassis and then you can raise lower, manoeuvre the axle as required. |

For the trailing arm bushes keep the wheels on the ground and chocked. This prevents any movement of the axle, making it easy to align the trailing arm bush with the axle bracket when reinstalling.
Releasing the taper on the A-frame ball joint can be tricky, one way of doing it is to first wind the nut off by one or two turns only. Then using a trolley jack and suitable piece of timber located under the A-frame, just in front of the axle and as close to the ball joint start to raise the jack. The taper should release before the wheels are off the ground (this is where it's important to only have the nut loosened by one or two turns, and certainly not removed altogether). Then remove the jack and wind the nut off the rest of the way and remove and replace the ball joint assembly, again with the wheels chocked and on the ground to prevent any rotation of the axle. |
