Rear ARB Anti Roll Bar Bushes - how to replace, with pics
Spent a couple of hours changing the rear ARB bushes today, so took a few pictures for anyone who might be interested. I fitted genuine LR parts as the last pair have done 100k miles, so can't complain really. Did consider Polybush, but decided to stay with genuine parts.
Firstly, I put the vehicle into off road height and removed fuses 3 and 26 in the engine compartment to stop the air suspension from moving once on the axle stands. Then jacked up the back and supported with stands under the chassis...

I think you need to have both sides off the ground at the same time to take any tension off the ARB.
With the wheels off it's easy to locate the anti roll bar bushes - in this picture of the rear nearside (UK) the ARB is just to the left of the orange body mount(bolts partly undone). The compressor housing is on the bottom left of this photo.

Tools I used for the job include 13mm sockets (3/8 and 1/2" drive), ratchet spanner, breaker bar, and WD40. The bolts are quite tight, and reluctant to come out due to corrosion on the lower threads, so don't expect to get them out easily if your vehicles been round the block a few times, as mine has! Try not to let the socket or spanner slip off too many times (easier said than done!) as the bolt head is quite soft and can round easily.

There isn't much clearance between the chassis and body in this area, so be aware that you can only use the socket for so long before it gets trapped by the bolt that it's removing. At that point you'll need to use the ring spanner, and probably an bit of pipe as an extension to get a bit more leverage.

Evenually, after much swearing and spanner rash, you'll have the 4 bolts out and be able to lift the anti roll bar up. I wasn't sure if there would be any tension on it, but with both hubs level it's fine.

To remove the old bush and bracket just slide it out along the ARB, and lever off with a screwdriver..

Old and new bushes, next to the bracket..

New rubber bush in place, held by bracket. It's quite a tight fit as the rubber is slightly bigger than the bracket, but with a bit of pursuasion you can get the bolts in and start tightening. I used new bolts as they were only a few pence each from Nick (aka The Large One), and saved battling with the corroded old ones again.

Tightened up on both sides, job done

No more clanking from the back end on rough ground any more, and i'm sure the ride feels better but that's probably in the mind Previously:

I have been getting the dreaded knocking sound for a few weeks now over rough ground and had intended to replace the rear ARB Bushes. Thanks for the fantastic guide and pictures

cool post
Just about to order my polybushes to get this done this week.i dont suppose you have pictures of the fronts!!!
Is it worth doing to tie rods(or whatever is at the other end) at the same time?

Ridgeback...did you change them both at the same time or unbolted one.. -done and move to the next one?Is this bar moves at some point ,so i would have to mark an old bushing position for a new one before I unscrew it? Also How one really knows that these bushings are bad?I have a clonking noise coming from a rear end but bushings look black with no corrosion signs,is it wear and expend kind of thing or am I missing something else(my car is at 80.000 miles, )I would like to order a polybushes , but in the States they nowhere to be found, maybe I ask one of the disco3 forum members...
I changed both at the same time, which I believe is the normal way of doing it. The important thing is to have both wheels/hubs level so there's no torsion load on the ARB. There are 2 collars on the bar, just inboard of the bushes, so they will ensure the bar sits in the correct position once it's all back together. If you crawl under the vehicle when it's in off road height, and grab the ARB, you might be able to feel it moving in the bushes. That's what mine did, with relatively little effort, so I knew they were shot. These are updated bushes I believe, so maybe no need for the polybush option? 80-100K miles is pretty good for LR rubber component in my experience!Previously:

The bushes just look like they are slight taller, so perhaps the new bush is designed to do away with the rubber spacer you can get?Bodsys Brake Bible

Well,mine does not move when pulled,still in the good shape?I have a terrible clunking noise in the rear end, especially when driving slow over bumps and pot holes,it is not just a one clunk , however,I hear a series of clunks ,like dull metallic noise,when parts move up or down or front and back,a couple of times,usually a fast couple of clunks.Initially , I thought about rear weights swaying back and forth , but after checking , it is a different noise they making...
