TD5 Trailing Arm Bushes

Just had an MOT fail on offside & nearside front & rear trailing arm rubber bush, and nearside front track rod end ball joint.

Am I right in thinking these would fit?:

DEFENDER DISCOVERY 200 300 V8 BEARMACH REAR TRAILING ARM BUSH WITH BOLT | eBay

Seems to say it's compatible with my vehicle but quite surprised they're compatible with 200s, 300s and td5

Track rod end ball joint I'm looking at this, seems to be alright, but should I replace in pairs or can I get away with one?

Any help would be much appreciated

They are all the same !! Think British , make one fit all !!!!!
Only need change the worn one realy !!

Cheers ferretboy nice one!

change them both sides parts are not a fortune, if one side is fecked the other wont be far behind.

If trailing and radius arms are synonymous, I am surprised everything is the same, as the disco2 ones have three holes and bushes whereas the disco 1 ones are quite different from what I have seen...

I went for polybushes for mine so they'd be easy to fit but wasn't pleased that the arm to chassis one required a press (or vice) to fit :-(

Yeah the bushes were the wrong ones! Only fit 200-300s.

Been refunded though and now have four old style going.. If anyone ever wants..
