beer can pullers - DIY

[shogun]

The tool is quite expensive, so if you want to make one on your own, here some examples:
I bought thos one from German Ebay for about 25 EURO. Is said to fit E30, E34, E32, therefore the flex diameter. But I am planning to do one rigid one.

what's it for?

rear subframe bushing = beer can


what's it for?

Getting it out is the easy part. How do you plan to press in the new bushing?

[winfred]

threaded rod and spacers properly applyed can pull it right in, i need to take a pic of the tool i made to do the rear balljoints in e38/39s i've since found it handy for one or two other things that i can't think of at the moment

... when I used the "official BMW tool" that baby creaked and groaned as we pushed that bastard in. Hardened center bolt with fine threads....

Jeff, was the thing lubed up? They only creak and groan when they're not greased. They also strip threads when not greased. So not having grease is a bad idea :D

I got some beer cans recently, they were us$30 each. I want to fill em with liquid urethane. looking at the bushings you can see there is space for it.

I'm thinking with the car on some jackstands and a floor jack underneath the bushing, it can be pressed in this way

this guy looks as if he's pressing the subframe bushing while the subframe bolt is in the bushing. I know I don't have to have the bolt there will I do it on an e34.

Is this method okay for my car?

..want to lube the bushings whatsoever. The BMW service manual clearly states only to use water to lube the bushings.

I can speak from experiance. The first time I did mine, we ignored the manual and use a solution of detergent and water to help ease them in. After both sides slipped out 1/2" plus, we followed the instructions and used water. No more slipping.

I'm not talking about the bushing, of course that doesn't get lube.

The threads on the BMW special tool, if used, need to be greased every single use. If they're not, they get messed up. We rent out the set; you'd be surprised at how expensive the parts are to replace when they get destroyed due to -- you guessed it -- no grease :D

Forgive me! I don't recall if we lubed the threads or not. I just recall noting how much force it took to run in the bushing.

Cheers!

whit,
the bushings are not greased of course.

But I found out that they slip in much easier when you warm them up in hot water (rubber gets softer/more flexible) and then add some kitchen detergent on the outside of the bushings.
You know, a 'good lubrication' often helps :p
