Ridiculously hard...but worthwhile, it's nice to know they'll never seize (if you grease the bolts like Honda failed to) I've done the rears on my S, with a view to renewing the fronts this month.

Powerflex ones are brilliant because they come in three parts, negating the need for a press to get them in the wishbone.

I have no doubt it's just as difficult on other cars...are you thinking of doing it on your BMW Gad?

powerflex bushes themselves - easy to change. it's actually getting the parts off, and old bushes out that make 'powerflexing' difficult imo.

worthwhile - noticed no handling differences, but happy to know they were the fraction of the price of honda bushes and will last practically indefinately. only had the 2 rear camber bushes done on the S.

I've done it on my S2000 DIY and it was a right PITA.

TBH the only reason i did it was because a) The bushes had seized thus geo out, b) You can't buy the bushes seperately off honda.

yes

there are six bushes involved iirc

I can see how it would be easy to do the two at the rear

I need to look at the four front bushes

I am good at taking things apart - so that won't be a serious problem

I am less good at putting things back together - so that needs to be simple

With Powerflex bushes the putting together is the easy bit.

The problem for you will be getting the old bushes out. Expect bleeding hands and a lot of swearing, followed by inappropriate use of one or more of the following;
Blowtorch, chisel, big hammer, bigger hammer, rock.

Did it on my mates CRX .. all suspension arms. Wasn't too hard with a 10 tonne press.

Another mate has just done his M3 with no issues.

pah!

I reckon it will take me no more than two hours........for the whole job

I know i can do the two back ones in under 30 minutes, so it's the fronts I need to check out

I have all of the implements you describe......plus a few others, so I should be ok

I was warned off them for this reason.

Whilst it will probably sharpen everything up and they won't wear out, isn't there a trade off in that you'll lose some of the damping of the standard bushes and transmit the forces elsewhere?

Good lock pressing those buggers out! A blowtorch might be quicker.
