  • A-arm bushings, which type?

    I have the front end of my '64 Daytona apart, and ready to order bushings. I noticed that some vendors sell the plastic-type, and others have the OEM rubber. What are the benefits, if any, of one over the other?
    BTW, I can't believe how much crap builds up on those a-arms!!!I think I'll take 'em to my local machine shop for cleaning...[B)]

    Delrin will outlast the rubber 5 to 1. Rubber will offer you just a little ride difference in the way that the delrin wil not flex one iota. I prefer the delrin. jimmijim

      After you clean them look for cracks. I prefer the UHMW Plastic for bushings, a little softer than Delrin but stiffer than urethane, with a better natural lubricity than either of the others.

        On that last post Alen said something about UHMW or urethane. I didn.t think anyone had urethane bushings for studebakers and what are UHMW?

            There are many who say that the Delrin bushing transmit more road vibration and bumps through suspension to the car and to the steering wheel. My car is being rebuilt and I'm going back with rubber OEM bushings.

                When I brought my 55 commander coupe back to life after sleeping for some 18 yrs, it recived new springs and derlin bushings.At the time this seemed to be the hot setup.Now this was the first Studebaker I had driven in many years so I had nothing to compair the ride to. It does seem like the ride can be harsh on the car but new springs too.At this time I'm considering oem bushings on the lowers to see if that makes any differance.I would have liked to use urathane but didn't think that was an option is it?I've read the opion of some of you on the forum about oem and derlin does a mix make any sence are there any other real options? The car does have around 11000 miles sence hitting the road again. As uasual the information from the members of this site is very much appreciated.

                  I would leave the Delrins in if I were you. Stock rubber is trash. There were 2 things that bothered me about the Delrins but have not proven true. One is the hardness, I thought that they might crack easier since they are hard and light. Second is you have to keep greasing them and most people do not do their own greasing and when they do take their car to some place like Jiffy Lube they don't even look in that area for a grease fitting and don't have the proper silicone grease for it.

                    The Avanti R-3 suspension, is the same as on my 52 Commander. there are bronze bushings, no rubber ones. the ride is not hard at all. I plan on replacing the front end bushings in my 63 Avanti with the derlin ones. I used them in a 62 Daytona convertible that I once had.

                      That sounds like a good alternative to too hard or too soft. [^]

                        Anyone that uses OEM rubber is nuts. Back in 1981 I did my 65 with OEM rubber and the 54. I have two sets of delrin sitting it the shop waiting for me to get a clear space. The car will be much more nimble with delrin then the rubber and it wont have to be done again in your lifetime.

                              28 years is probably 18 years longer then the OEM was designed to last. So, I'd say you got over on them. I have repaired the mounts and frame sections on and around the cross member for cracks on several cars with the delrin bushings. I attribute these repairs to the added rigidity and reduced flexibility these bushings cause. The first one, a 57 Golden Hawk, had only had them installed for about 5 years. The owner told me that there had been no cracks prior to the last rebuild. I got similar stories from the other owners as well. Seems to me that the light weight frames our cars have don't tolerate these things to well. Of course, these were all 53 to 60 hawk and sedan. I haven't seen any later models equipped with these, yet?
