Just butcher them without damaging the  bush housing on the diff.

Hi Steve, I have done this before.

What you need:

1 long bolt (full thread) with nut that fits through the hole in bush

2 pieces of pipe-1 that is internally big enough that the bush can slide up it (I will call A),and 1 that's the same diameter as the bush ( B )approx 50mm long

2 x piece of flat steel 40mm longer than the diameter of (A) and ( B )with a hole drill half way along to suit bolt

 

Steps:

Once under car at bush, place bolt through longest piece of steel, then through (A), through "head" of bush, out the other side of bush, through ( B ), through other piece of steel and place nut on bolt. Tighten nut centering (A) so it doesn't touch bush, (B)fits exactly on bush. Tighten nut and it will press out.

 

To install

Turn your jig around and do the same to press it in. You could even not use (B)here and just use a piece of 60mmx 60mm flat steel with a hole in the middle. So bolt goes through longest steel, through pipe (A), through housing mount,  through "foot" of bush, through steel plate. Tighten nut and it will pull in.

 

Hope it helps. Bit of setting up getting the right pipe, but once you have it you will be right

An air chisel/hammer will do the job in a couple of minutes if you don't have time to make your own puller.

 

Something like this.

The threaded puller is a better idea as after changing a couple of bits it will also allow you to install the new ones!

I drilled out the rubber, then used an air chisel to fold over the ends and just belted the outer case out.

  

 

Fitting the new ones i made my own tool, a long bolt, nut, two large washers bigger than the bush and some smaller washers for packing.

 

I tightened the nut and then give it a whack from the small washer end with the hammer to seat the bush.

 

When i did the trailing arm bushes i used a fence post cap as well.

 

 

put the head of the bolt in the vice, a block of wood in the middle of the arm  and tightened down with a spanner.

Good on you Steve,

 

sure is a tough bugger, as said, butcher them out,

 

as your are not going to be using them again.

 

 

Always better to do a job with a straight back.

[WhaleOilBeefHooked]

Yep drill multiple holes through old bushes and then remove the rubber, Makes removing the steel outer case a little easier......

[EunUCh]

Always easier with diff out,a few more bolts to undo but it is better that on your back under a car,just end up getting wild with it,no room to swing a cat

let alone a hammer,and you can always check a few other things when it is out.

[TerrA LX]

nothing like pulling the third member out for a good going over.

[My390]

These old threads have a lot of great info. Made a puller and got the rubber bushes out fairly easy.

 

the steel outer case is rusted on fairly solid. Any other tips? Or just keep at it?

Soaking it in WD40 is a no brainer but you've probably already tried that.

 

Some people try and loosen the mechanical friction caused by the tight "fit" by carefully running a cutting wheel (or a hacksaw blade, pencil grinder etc.) through it with the hope that it'll weaken and collapse a little.

[My390]

Thanks Heath. They have been soaked in WD40 quite a few times. So far I have got 3 out by using the long bolt puller as described and bashing the sleeve out carefully. I will try cutting it a little. Only 5 to go.

[76lxhatch]

If the inner rubber is coming out and leaving the bushing shell behind then your puller needs a larger diameter so it pushes on the shell itself rather than just separating the rubber part.

 

Once you've separated the rubber the easiest way to get them out is destruction, just attack with an air hammer/chisel and collapse them inward to avoid damaging anything other than the bushing shell.

[My390]

All 8 bushes out no worries. I found that a small section of fire sprinkler pipe was the perfect size to get them out. Lots of WD40 and some gentle persuasion with a hammer.
