Title: Powerflex Bush or New Wishbones ?
Post by: Proz on 27 February 2011, 12:32:44
Hi again
Im getting the beginings of a slight knocking at the front again  :-/
Drop links were done certainly less than a year ago and its had both track rod ends and steering idler in the last year or two so im assuming the wishbones are failing . I've had the car for nearly 3 years now and they have never been done and i dont know if they ever have .... so ,
Should i get new wishbones or Powerflex the front bush ?
I saw a clip by Turk i belive it was doing them without taking wishbone off the car and using a blowtorch type thing and hacksaw to remove the old bush  .
Looks reasonably easy ish and i would have a go if i can source a blowtorch thingy .
Does the camber etc have to be re-checked if only the front bush is done and also would this cure my knocking ?
I would hate to do the bush only to find out its still there .
I would get the kit that includes the anti-roll bar as well .
Price of the kit including anti roll bushes is about £70
I could get new wishbones for that  ::)
Im asking a lot of stupid questions here and i should really go underneath and have a poke about for play etc .
Decisions Decisions  :-/

I would get a pry bar or big driver between wishbone & chassis to see how much movement there is first, i think you would have noticed serious handling issues  if they are knackered enough be knocking

I was hoping not to have to change the whole wishbone as i think thats beyond my skill or toolbox  :-/

Give it a go Proz.

It seems as with most replacements to just be unbolt/remove /replace...the guide gives all the information and the only bit which would really be beyond us mortals is the correct alignment.

Much better satisfaction knowing you have done a good job and saved yourself a fair few pints .

I intend to replace mine shortly and am also no mechanic but will give most things a go...worst that happens is you do it again, correctly.

The only problem i really have is that i can only do jobs at work on the weekends as i dont have suitable area to work in at home or jacks / stands etc ... The good side of doing it at work is there's always lots of people about  :y
Im just undecided as to wether to get new wishbones and replace or to just try the front bush with Powerflex .
Im sure i read somewhere on here before that just doing the front bush doesnt affect camber etc where changing the whole wishbone obviously does  :-/

Whilst I accept just the front seems to get the most abuse,probably why powerflex offer it as a replacement,I would then question the life of the remaining 2.

Can,t answer if alignment would still need doing if just front replaced,but I think for peace of mind and the potential of needing new tyres I would get it done anyway.

Work is a great place to do repairs especially if you are on wages at the time,I am fortunate that I do have a large concrete drive area but it is not under cover so my repairs/maintenace seem to be more weather related than planned.

My advise would be to replace the entire bone and drop link then you know it is new..just my opinion though.

I replaced the wishbones with ebay specials with a bit of help courtesy of Elite Pete. These were done and torqued correctly, after just short of 20K miles (5 months) im thinking of replacing the front bushes with poly as its getting a bit wandery :y

Agreed, I've just had to replace drop links after less than a years use. If it's the drivers side, you can especially feel the knock through the pedals and even a slight rutt in the road will make it knock. It's very annoying. They're cheap to replace so i'd try those first before wishbones.  :y

When it comes to doing wishbones, it can be a real pig of a job (if you're not experienced). I've done them myself and they didn't last very long, probably due to incorrect torquing procedure. Some of the guys did mine at Newent last year and there is a definite knack to doing them (it's easy when you know how of course). I would recommend getting someone experienced to help you first time round. Get a 4-wheel align done after too, it's really worth it.

A few comments.

The rear wishbone bush seems to last very well, certainly for 80K+ of average miles.

The droplinks, beware of the mega cheap ones, they dont last and hence why why say go for the Febi/Bilstein or FAI ones as they are known to be ok.

So, for the original posters query, if the rear bushes look ok (they probably are ok) then simply chuck some polys in the front.

Depends what you find when inspected. There are more causes of a knock than just drop links, anything with play in the steering and suspension can knock, top shock mounts, steering knuckle, wheel baring, track rod ends etc etc. Although drop links are a favourite.

See the guides, arm yourself with info, get under there with both wheels off the floor and jiggle/wiggle everything for play.

Inspect the rearward bush as Mark says, if theres no visible splits you could  just do the fronts with poly if you wish, although the fronts need checking too. Go from there.

Diagnose, replace, set up, then fit new tyres if needed.

I'm no expert mate but very careful if you put powerfelx Polly bush's on your car cause if you have a fairly old omega or any car for that matter I have heard and seen that because they are a lot stiffer they can cause your chassis problems (like cracks etc) I have seen a few of my mates cars in the past that this has happened to and then they have had to get it all sorted and have switched back to the o.e.

This was posted on a similar thread last year. Has anyone else had chassis problems with poly bushes?

On the one hand, I could imagine that being possible, bushes are there to allow movement obviously, but also to absorb shock and vibration. Stiffer they are, the harsher it gets, but also more accurate I hope, that's the trade off we're dealing with.

But on the other hand, those that have polly seem happy, and Mr Dtm says they are fairly compliant....


Re my own car, I may fit polly, out of interest mostly. If too stiff then fit my pre pressed with m3 bushes wishbones ... LPG first though.

So on balance, it sounds as though there are no serious issues, plus, hopefully, longer life. I was interested also to read Tony's response to your thread on WIM, suggesting that fitment of polys should not affect the rear bushes. :y
