Installing Lower Control Arm Bushings - Tool Alternatives

If I don't have a shop press and I don't want to spend the money on the special MB tool, is there another way to press the bushings into the lower control arms?

Thanks,

Scott

I used a vice. A large clamp would work too.

I used a piece of 5/8" allthread and with a stack of washers. I suppose a big enough bolt would work too.

clean the inside with very fine sandpaper (i used 1200 wet sand grit) and spray out with brake cleaner.

definitely us a vice. and use soft soap to lubricate the bushing rubber as well as on the inside too.

the one i dindt figure out was what to use to do an outer crimp of the inner sleeves. i ended up using a plumb bob. didnt turn out so great, but doesnt fall out either

To flair the tube I made a tool out of a lug nut from my truck and a long bolt. It worked great. I had to buy a pack of $17 pack of 5 bolts to get the one I needed, so I would be willing to sell some of these tools, say $6 shipped.

My first attempt at flaring the tube involved a 1/2" socket extension and my vice to squeeze it, however the back side of the tube got pressed away from being perfectly flush with the bushing while I was flaring it, so when I tried to put the bushing in place the mount on the body of the car damaged the aluminum tube and I had to buy another one (from Germany )

To flare the Aluminum tube I used 2 sockets that had tapers to flare the tube end and a large C clamp to apply the pressure. I read another member used a large tapered punch to do the flaring.
I also had to file it flush after the flaring was done.
The factory manual tells you to use no oil to lube the bushings and to use a vice to press the bushings in. To lube I have read of soapy water or KY jelly.
To press the bushing in I used the threaded rod and large washers that I already had those things from another project just as PatricdeBoer did.
I am about 1/2 way through my bushing replacement job.
Unexpected trouble removing front Lower Control Arm Bushings.

It also helps if you put the new bushings in the freezer for a few hours to shrink them a bit. You might heat the bushing end of the control arm a bit with a torch before you press the bushings in too. You'd be surprised how much it helps- sometimes it's enough that they will slip in by hand.

A vise will suffice but make sure you LUBE THE BUSHINGS up or you could destroy them putting them in. Soapy water or orange hand cleaner works( the non toxic kind)

5/16" all-thread with nuts and a stack of washers
cheap Harbor Freight 3/4" dr. sockets
...........and the best lubricant......KY Jelly (won't harm the rubber and water-soluble which keeps the bushing in place after installation)

The later W126 may be different, was there an aluminum tube in the center of the bushing? Did it have a bell shaped flair on one end? I don’t think the LCA/bushing would fit back into the mount on the body if you needed to flair the tube and didn’t.

The 123 parts are different so require a different way to assemble.
