replacing lower wishbone (a-arm) bushings

Hi all, I'm in the process of getting things sorted for an upcoming front end rebuild. While waiting for the last of the parts to arrive, I'm already going thru Vintre's excellent DIY. Now with no disrespect to Vince, he took the arms to a shop to have the old bushing pressed out and new ones pressed it, and I'm trying to get a sense of whether these can be managed at home by any means short of a multi ton press. If they are manageable enough to replace myself, I'd like to know, and may want to do them to save the time of having to wait for a shop to do them. If you've done these at home and succeeded I'd like to know how. If you tried and gave up, I'd like to know, in which case you'll help me concede defeat and I won't waste my time.

Thanks

I took the first set to a garage and had them press them.
The second set (on my other car) I tapped out, over an open vice, having read some advice to that effect.
They came out really easily. You have to make sure you tap them the right way, as they push in against a stop, but you're probably on to that already.
The new ones were similarly easy to press in with the vice.

Put the new ones in the freezer for a day or two before putting them in. They will go in much easier.

I've used a shop press and hammered them out with a socket over an open vise. I've also pressed them in with a vise and I've also pressed them in with a press. Its not a really difficult job. Freezing them does make it easier. Freezing works for anything you have to press into something. Trailing arm bushings, Sway bar bushings, lower ball joints on transaxle alfa's, etc.

Hi, i did this during last christmas break. Were you able to find the bushings? at the time, all the usual suppliers were out. I did end up finding some on ebay.
To remove them, i didn't use a press since i don't have one. But the vise and hammer with a socket worked just fine.

My $.02 worth: If you are planning on doing a suspension makeover I would invest in an H Frame press ($129 @ HF ). It makes easy work of any bushing project, is quite versatile in general, doesn't take up much space and if you felt you'd never use it again you could sell it for half price...

I second that recommendation. You will be amazed at 1) how easy it makes suspension bushing removal/installation, and 2) how many other uses you find for it.

Sure, you can freeze / heat / beat / vise, but at the end of the day, a press does it quicker with less risk of damage or injury.

Just removed today. Was surprisingly easy with the he 12 ton press, so easy that id think tapping out or vise would have worked as well. Sway bar bushes much harder for rears I assume fonts would also have been except links damaged so bought the links with bushes in place. Without a press I'd of had to cut those out. Lots of uses for the press, a worthy purchase..

No, I don't agree. Things seem to come apart a lot easier when you apply a steady, constant force (like from a press) than they do when you bang on them. And that press is exerting a lot more force than a vise.

Ok, looks like I'll be getting a helping hand from another local Alfisti that has access to portable press. So its just a matter of figuring out whatever bits and pieces I will need to use with the press. It looks like the install of new ones is straight forward. However a specific sized tube of some kind will be required to push out the originals. Any chance one of you guys know or have spare parts that can be measured and tell me either the inside diameter of the arm, or better yet, the outside diameter of the end cap.

Below is a video of the wishbone bushing R&R. It's not rocket science. As for as tube diameters, I would suggest using deep well sockets. If you have a decent size set you'll find a couple to use.



The most important thing is to recognize that the wishbone has a lip. So you push the old bearing out from the outside side of the wishbone toward the inside. Obviously installation would be the reverse.

Also, when you are pushing the old bushing out you may find that there is a lot of force at first. Then a bang and the bushing moves out with little force thereafter. Perfectly normal but the bang can be a little bit of a surprise if you're not expecting it.

Which reminds me of another benefit of using a press, rather than a BFH: The constant force of a press won't damage a socket (or your parts). Beating on them with a hammer will definitely cause damage.

Thats a good video, thanks for sharing.

A press would be nice to have but they are expensive over here (no HF) and take up a lot of room for the 364 days a year they are not used.
I haven't found anywhere that rents them out either.
