Topic: Fitting suspension bushings Posted: 19-March-2006 at 04:40 |
My rear suspension bushings (haven't looked at the front) look pretty worn and it would probably be a good idea to replace them. Are there any front or rear bushings that I would need a machine shop to press out and in? Thanks |

The big subframe bushes ahead of the rear wheels really need the correct tool to replace (some clever bods make their own). If these are worn the car will feel very peculiar to drive as the rear wheels will be steering too.
Other bushes are more straight forward to replace. Have a look at the diff mounts while you're under there as these can get a little tired too. The front bushes tend to wear more & it's a common dodge to replace some of the components with uprated items ie. 750 bushes which have to be machined down a little. See BigCoupe.com tech articles for advice. Don't forget the anti-roll bar bushes too. Some people swear by poly bushes which are stiffer than standard bushes. They last longer but do make the ride harsher & noisier. This may or may not be an acceptable trade off for you. If you've ever been in an M3 you'll see how stiffer bushes give a "tight" feel to the suspension. Replacing all front & rear bushes is an effective way of getting the "as new" feel back into your car. |

Thanks for this info. I think I'll go with standard bushes. So I'll just pull the rear wish bones out and take them to the shop and the rest I can do myself? I don't need a press for any of the front ones? Thanks |

Ok, had a further look and have two questions: - How do I seperate the rear wishbone from the hub? Do I need to take the hub apart? - What's the small "bone" going from the outer joint of the wishbone to the body for? It's fitted with bushings but I can't really figure out what the purpose is? Thanks |

these are the 'pitman arms' or 'dog bones'. They provide for lateral trailing arm control and also affect the rear toe settings when cornering. They are only present on E28-base chassis 6ers, E12 base ones did without. If they are knackered the handling (especially turn-in) will be absolute pants. They are a doddle to change, and aren't even a lot of money. I'd advise you re the other bushings, but its not a job I've had to do myself.... cheers

Brucey, thaks for all your help. When you say replace do you mean replace the whole pitman arm or just the bushings? I think I'll remove the wishbones with the hubs still on them. Are the bolts on the outer CV joint usually hard to get off? Thanks! |

the whole wee pitman arm is replaced- Dave J did his a while back and posted some pictures on bigcoupe.com IIRC. The CV joint bolts are best released with the car still sat on its wheels (they can be rather tight), but undone completely when the the car is in the air and you can turn the wheel/shaft; a ball-ended allen key is an excellent idea as it gets a bit tedious otherwise.... When removing the trailing arms, I would advise removing the whole driveshaft as otherwise you may strain the rubber boots a bit much, BTW. cheers

I can't believe the brake lines go through the wishbones twice! What a nightmare. |

Ok, I've given up on doing the wishbone to subframe bushings. I'm looking into cutting of the small brackets that holds the brake and fuel lines and remove the lines to get the screws out. |
