So on our last trip I noticed a squeaking when suspension moved, noise coming from front driver’s side. I suspected upper control arm bushing so I set about replacing them on that side. It is a pretty straight forward job, and here are a couple of diagrams illustrating where the bushings are.
I jacked up and supported driver’s side front of van and removed wheel. When I detached the upper ball joint I could move the control arm by hand, and the squeak was there. 19 mm nut on one end of camber adjusting bolt, other end is 14 mm socket. Arm off and in the workshop.

Other side of bushing. There is a good chance these are originals.
Here is one of the new bushings. Vaico brand, I don’t know where they fall in the quality line up, but I got them in trade for some used vanagon parts. There is a great Samba thread on UCA bushings here.
I wondered if an O-ring would help keep any grease in.
Then I tried some silicone over the O-ring, a variation of what Tencentlife did in above mentioned Samba thread. I ended up removing the silicone and adding a second O-ring.
Now getting the old bushings out. I don’t have a press so I used a bit of aluminium tubing, a biggish socket, and an old 2WD control arm bolt, and a heavy hammer to drive the bushing out.
Look at that clutter. Workshop is in a real sorry state.
Old bushing out.
Bore of UCA where bushing fits. On the syncro it is a simple press fit, no spot weld needed.
Using a vice to press new bushing in.
Part way in. Ok, you’ve noticed that I painted the UCA. A very
casual crap job and wasn’t needed (original paint still good), but I had a can of orange paint and I thought it might look cool. Overnight drying time was not enough, paint still soft, came off here and there. Perhaps I should lock up the paint.
A bit of pop can in UCA to keep a large socket in place while bushing driven home.
And the other bushing pressed in.
Out at the van, rear of support where bolt goes through and eccentric washer sits.

Rear eccentric washer in place. It was a fiddly job offering up the UCA into correct position and not have the washers fall out.
But in it went finally. Everything re-assembled. Guess what? I still have a squeak!
Next post will deal with camber adjustment and perhaps finding the squeak.
