Are you replacing your stock ones with rubber OE ones?

[Digitalwave]

Take it to a shop.

[grapedrink]

Do you have a press? Take it to the shop then.

Or he could just take it to machine shop and have the parts that need it pressed. Then he could do the rest of the work himself.

Some of you arrogant jackasses seem to forget that you were once new to working on cars. Someone asks a noob question on how to do something on their car, and all they get is "take it to a shop". If all you ever do is take your car to a shop, you won't ever learn how to do it.

NC325iC, ignore half of these wanks, get a Bentley manual, and learn how to do the work.

You'll definitely need to take it to a shop to get the bushings pressed out and new ones pressed in. If you don't take the whole CA out, it's nearly impossible to get the new bushings on unless you have the BMW tool.

[DanGillan]

1. unbolt CAB lollipops (16 or 17mm bolts, 2 on each lollipop)
2. press off CAB lollipops with CAB's
3. press out old bushings
4. press in new bushings
5. reinstall CAB lollipops with new CAB's using sylglide or something similar

your going to want a shop to do all the pressing for you, doing it in a vice can be sketchy and you probably dont have the right tools do actually do it right in a vise. good luck.

[NC325iC]

yeah i think i can handle gettin the lolipops off then takin it too a shop, i have a bently i was just wonderin if anyone had any tips, im not completely worthless when it comes to cars guys.
thanks to the guys that said something other than just take it to a shop.

I did it without taking it to a shop, my dad replaced cabs on e28 without going to the shop. I dont have a press, and it can be done (don't recommend my method).

The right way to do it is to have the pressed out, because you dont want to mess up the lip of the lolipop. Here are a few tips,
1)repair manual says to center punch the end of the control arm, but its kinda difficult, I drilled a small hole in the end to have a groove for my puller to sit in. If you dont have a 3 prong puller you can rent one from an autoparts store. Place the puller on the lolipop and start tightening, it should eventually pop off. With the bushings off you cen easily take them to be pressed out. Does not cost much from what I hear.
2)I would recommend getting a set of upgraded poly bushings, the rtrs bushing will slide right onto the control arm without pressing them in.

[cahomey]

If your not going to use the rtrs bushings, use a large socket and hammer the lollypops on to the arm..

And don't forget soapy water.

You are worse than a post whore.

Whenever I see a post of yours... your selling something. :roll:

my urethane CAB just slid rite on the CA without any force or lube...are my CAB just filthy slutbags?

right, the bushing should slide right on the control arm. Its getting the bushing inside the lollipop that requires the soapy water and mucho force to slide in.

There is no way in hell you can press a bushing into the lollipop w/o using a hydraulic press. You need about 6 tons of force.

Only the rubber bushings require lube, the urethane ones should just slide on.

Jackass. First you post an ignorant "take it to a shop" post, then you go and actually answer the question. Maybe you should have posted that in the first place Danny. :) Use your powers for good instead of evil....

As for the CAB's, you should absolutely get them pressed. Too much of a chance of putting them in incorrectly and/or damaging them in the process. It doesn't cost much - any reputable shop can do it for you, and it doesn't take long.

WTF?
his post added infinitely more to this thread than yours did. Mine as well, but I believe that Alex deserves a defense

I've done it twice.. my dad did it once....

Your brackets must be wasted then, because your bushings need to be held in a little tighter than something you can push in with some soapy water.

[nando]

is he talking about pushing them onto the control arm or pressing the bushings into the brackets without a press? if the latter, I call BS. I destroyed a $40 puller after getting one bushing halfway into the bracket. then I took it to a shop and they took 15 minutes to press both sides in and only charged me $20. :roll:

I've also tried the freezing method (heat up the bracket, freeze the bushing). it doesn't work, because the bracket isn't actually round. it's slightly oval, when you press in the bushing it deforms the bracket which holds it in tight. putting it in a vice works no better..

to make it easy I bought a set of used brackets for $35. that way I can have a set with new bushings ready to go and just hammer them onto the control arms before I put them in the car.

[BahnE30]

the control arm doesn't have to come off the car does it, mine are trashed and i have a press just not 100% on what needs to be removed.

[FrustratedMunky]

From what I understand, it's POSSIBLE to just unbolt the lolipop and slide off the end of the control arm from the bushing. Then, get the old bushing out and the new bushing in (however method you want to use) and then slide it back onto the control arm with some dishwashing liquid and let it sit for ~24 hours to let the dishwashing liquid dry up before you drive, or else you can possibly have it slip out or something. It might be just the luck of the draw as to if you are able to just pull off the bushing from the control arm, without having to take off the actual control arm itself. I plan on doing my M3 offset CAB's this coming week, and I'm just going to take off the lolipops and HOPE that I don't have to remove the control arms (although it doesn't sound terribly difficult) and if I do, I'll do it.

Someone please correct me if any of this is wrong.

[nando]

you can easily do it without removing the control arms. remove your wheels to take weight off the suspension, get a torch and heat up the old bushings, when they are soft enough you can pull them off with your hands. however, getting the bushings back on the control arms without removing them is much more difficult than if they are out of the car.

[BahnE30]

well my old bushings are complete trash ie, 1/2 of the square rubber chunks are missing out of both. and i have another set of lollipops so i think i'm going to end of freezing the spare set with the bushing in place and using some white lithium grease on the control arm and sliding them on, hopefully all that should prevent me from having to remove the control arm.
