Replacing front radius arm bushes.

**langy** · 7th June 2007, 12:42 AM

After some mention of this by Discowhite, I figured a new set of rubbers for the radius arms were in order.

Special tools required: 24mm socket and spanner, 29 mm socket (for the single rear fitting), small drift to get the bolts out and back in. No need to go into dissassembly, except to say you will need to drop the track rod to drop the radius arm out, and if you have a diff protector, it will have to come off as well.

Note: The axle will move back when you drop the radius arm, it is easy to push back into position provided you are on level ground.

From left to right: The old damaged bush, and the other undamaged old bush. New bush NRC 4514, which is specified for a disco, and ANR6971 which is apparantly the new design for Defender 90's. The new design fits just as well, and has serrations on the inside of the bush, presumably to hold grease in place ( I greased up all surfaces of the bush and shafts on re-assembly) . They are even cheap at $7 each ( The older version is $14) from Karcraft.

And, for owners of Disco's with 300k on them ( As is mine) this is how the front bush set looks like. They seemed in fair condition, so I left them alone.

Result: Decent inprovement in the feel of the steering and reduction in steering vibration at 90k.
Time taken: Roughly 1hr total.

Still should have done the 4 front bushes, even though the appear ok visually it can be very decieving

Ditto...

Not as easy to replace though (unless you've got a 10tonne press in your garage...

)

10 tonne be buggered. I had to use a 50 tonne one. The gauge was reading 40 tonnes as they were going in.

and those triple shell ones should go if you want the front end to flex

Defender ones are only twin shell and help a lot, or if you are into harder stuff the Haultech ones.

I thought you would need a big press to do my D2, so off to LandRover to have them do it.

When picking the car up we heard a loud banging coming from the workshop, looking in we saw the mechanic bashing the bush in with a large hammer and socket

If i'd had known that, i would of done it myself

40 tonne going in

I thinking maybe you should have sprayed a little CRC or similar prier to fitment, I struggle along with a 6 ton supercheap job, trust me that spray makes ALL the difference

Yea, I'm after a shop press if anyone knows where a cheapy is

i have always been lucky to have two cars. so what i do is take off the radius arms and then go down to a garage and get them to push them out . Do it for a drink ($20)
Then i put in poloybush ones. Which you can do at home
Easy job done

If ya stick the new bushes in the freezer for a few days and make em nice and cold they press in nice and easy as the freezer seems to srink em a pooftenth and a little lube and they press in easy

yeah tahts the go - shrink then in the freezer and then warm the radias arms hole with a blow torch or similar... be careful not to apply too much heat n ruin the lot! they will nearly fall in .... or thats how the theory goes
