    Joe, yes I swung the a-arm up and away from the inner fender/splash apron.

    When I do a whole front end rebuild, I'll use a combination of the air chisel and hydraulic press/spacers (depending on how easily the bushings come out) for removal, and the press and the spacers for the bushing installation.

    Before I got my hydraulic press, I would take the a-arms to work and use the big arbor press. Our hydraulic press at work was WAY WAY too big to use on something as small as these a-arms.

    Thanks Paul,
    I have always just headed for the bench-vice with 'A' arm in hand, and used a dulled air chisel; earlier days, a ball peen and dulled chisel. It never occurred to me to try to do it up under the fender-well, and not sure I could, with my tools of choice. I'd also think it a bit cramped under the fender with your tool set, and probably would be reluctant to even try. But that's just me.

    Did you spin it around 180 degrees, to work on it from just outside the fender or something? I am having trouble visualizing that, but suppose it's possible.
    Thanks Again,
    Joe H

    OK, for those asking, here are more details......................

    Topper: I'm pretty sure I used this bushing remover/installer set to remove the bushings. There is no reason you couldn't use an air chisel, I've used those before. But I was doing this on the carport well away from my compressed air source, and was probably too lazy to drag my little 50-year old Craftsman wheeled 'backup' compressor up the hill from the other end of the house, hook up a power source, etc. The tool I used only removes/replaces one bushing at a time, so I didn't need spacers. (I have a set for when I use the hydraulic press.) As far as pictures, I looked but apparently didn't take any, and this was before I started my YouTube channel so there is no video either. I'll put in links below of our own Clark (showbizkid) using this tool on his blog site, and also a thread here on the SDC forum.

    doofus: The tool I used is shown in the pics below, double click to open large versions. If you search on the internet on " Upper Control Arm Bushing Service Set 20718A" you will get a lot of hits, mainly on this part number. The price sure has gone up since I got this set! Here is a similar set on Amazon for a reasonable price: https://www.amazon.com/8MILELAKE-Con...a-858563954047 By looking at the instructions, and the pieces in the set, you can probably make something similar out of a large C-clamp and scraps of pipe. Or get a similar bushing/ball joint set from Harbor Freight and modify the pieces as needed. As mentioned just above, the chain parts stores have various kits for bushings and ball joints that you can borrow, and probably us various pieces to make this work.

    Forum thread: https://forum.studebakerdriversclub....ushing-install

    Hope this info helps. As mentioned, the reason I took this route was to prevent the almost inventible project scope creep that would end up with the whole front end in pieces, rather than just replacing the two upper inner bushings on one side. And it worked well, got the bushings replaced and did a quick front end alignment, all while the car was sitting in the carport.

    I bought one on Amazon. Search for control arm bushing removal tool. There all seem to be the same. Buy the cheapest. I did not try to use it with the arm on the car, but it worked great for both the upper and lower arms.

    Paul, was the U-joint tool long enough to go from one end of the a arm to the other? Did you use an air chisel to drive out the old housing? Do you have any pictures? I had a bear of a time replacing my bushings. I also had to make the spacers to keep from bending in the "ears" of the arm while pressing in the bushings. I'm always interested in flat rate methods.

    Yes, the last one I did was my '54 sedan. I was doing an alignment and found the inner bushings on the passenger side had a lot of deterioration, but everything else on that side was fairly good. Didn't want to end up with major scope creep and end up with the whole front end apart, so just replaced those .

You can unbolt the rear of the upper a-arm bracket from the crossmember (2 bolts) and replace the bushines using a bushing & balljoint remover/installer kit that can be rented at the chain stores.

    The lower inner bushings, and the upper and lower outer bushings, are much more difficult to replace since you need to deal with the energy stored in the springs.

    Just reach up under the fender well and place your fingertips on the washer, and feel if it is centered on the outer metal ring of the bushing. If it's noticeably off center, probably need bushings. You can do same on the lower bushings. The large washer OD is only slightly larger than the bushing shell, and it's easy to feel if it's off center. Doesn't need to be perfect, but if more than, say, 1/8" off it's time to replace them.

    Replace as a set, upper and/or lower. Whatever you do, do NOT use NOS bushings, as the old rubber will disintegration less than a year. Unless it's a TQ.

    The wheels will tilt inboard at the top enough that a good eye from 8-10 Ft. away can actually SEE the Negative Camber.

    Can you take the bolts and washers out of the ends of the bushings and look at them? They could be off center and the rubber could be shot.
