mrrodriguez77 Posted September 3, 2020 Share Posted September 3, 2020 I'm in the process of gathering goodies to custom make my own rear control arm bushings but pickins are coming up slim. Rock Auto no longer has anything in stock, I found a pair of Centric Caddy bushings through Amazon and none of the locals seem to have anything. Cross referenced all the part numbers form the various posts from RockinRiviDad, JRRivi64 etc. I really don't want to shell out a heap of cash if I don't have to. Thoughts?

XframeFX Posted September 3, 2020 Share Posted September 3, 2020 I could be incorrect on this as I've been involved in my project only since 2015. I believe GM Serviced the rear lower control arm as an assembly back-in-the-day and I don't believe the aftermarket ever offered individual bushings. However, Bushings for the Panhard Rod are available. There's been many threads on this. Would be nice to have repro parts on this. If so, won't be cheap in order for a mnfr to go to the trouble of doing it. Link to comment Share on other sites More sharing options...
RivNut Posted September 3, 2020 Share Posted September 3, 2020 Well that's a downer. If you have the part number, have you tried other sources? XframeFX - If you weren't aware of it. That OE lower control arm bushing has not been around for a while, but someone figured out that some aftermarket firm was using the Cadillac bushing and a 3/8" spacer to make a bushing that would work. We've been making our own out of the Cadillac bushing and stock rod with a hole drilled through the middle. Gotta find more of the Caddy bushings. Time for all of you Hercule Poirots out there to start snooping. 1 Link to comment Share on other sites More sharing options...

After more scouring, Autozone sells the Rare Car part #15096 piece @ $52.49 ea. and ProSteer Part# FB669 (from RockinRiviDad's original post on the subject) is @ $28.49 ea. Raybestos is no longer available and neither is Dorman. This might be what we have left as I think I scooped up the last Centric pieces. Link to comment Share on other sites More sharing options...
RivNut Posted September 4, 2020 Share Posted September 4, 2020 Does anyone know the old Moog or other main line brand part numbers? I have a friend who manages an Advan e Auto store. He's found things for me using part numbers that aren't in their computers by " year, make, and model." Link to comment Share on other sites More sharing options...
GCC Posted September 4, 2020 Share Posted September 4, 2020 I did this last year and it was difficult to track anything down. The only thing left available that I could find is Centric 602.62052. I ordered from CarId, looks like they still have them here, $10.46 each. You'll have to reduce the diameter slightly and use a spacer as described in other posts. The simplest spacer was just to push out the sleeve from the old bushings and cut off the necessary length. 1 Link to comment Share on other sites More sharing options...
TKRIV Posted September 4, 2020 Share Posted September 4, 2020 Frustrated with the 2nd rate offerings a small group of 1st Gen Riv enthusiasts with OEM auto industry connections have been in development of an exact replacement of rear bushings. Tooling completed and about to evaluate full production samples, and yes we‘re excited. These are dimensionally 100% as original and with the same hardness rubber. Volume production is being done by a specialist (not Chinese) manufacturer of suspension components with facilities approved and used by Toyota and other major manufacturers. After many months we’re hopeful these “made for purpose” bushings will be available mid November. Pricing is yet to be determined but we know will be well below any of the current sub-standard offerings. They’ll be available in pairs so let us know your interest or feedback.

telriv Posted September 4, 2020 Share Posted September 4, 2020 Myself ALSO as my rear suspension has over 300K on it. Although I don't see anything wrong with them I'm sure they will be marginal at best once I dis-assemble. Do we only need two for the front where the control arms attach at the frame??? AND, for the rear of the control arm where it attaches to the diff. housing??? Which if so means four are needed to do the job properly. Thanks in advance. Tom T.

Cheers Tom Kunek This is exactly what should occur, band together and justify an exact replacement. No performance polyurethane, just OEM plain & simple. I'm 'done' with experimenting even if I had kept spare control arms. No bushings from another app with added-on spacers. Please count-me-in Tom. It will be a future project following a transmission swap (OE installation). But I'll purchase the parts if they ever become available. John B.

RivNut Posted September 4, 2020 Share Posted September 4, 2020 TK, I know that this is a project that will take a while to get totally under control, but have you thought about having a U.S.A. distribution point so each of us doesn't have to pay S&H from Australia? Question to all of us non-downunder folks. Why is it that the Aussies are the ones who take on these kinds of projects? Link to comment Share on other sites More sharing options...
RivNut Posted September 4, 2020 Share Posted September 4, 2020 I dragged out the '64 chassis manual to see what was said about replacing the lower control arm bushings and hoping for some detail on the bushings. The procedure detailed the sequence for removal of springs, alignment of support under the carrier, and using a brass drift to remove stubborn bolts. (But no details on removal of the bushings.) And no specs for the bushing. I was also looking for information on whether the front and rear bushings were the same. Nothing. I then looked at the illustration and got to wondering about support for the adjustable upper control arm. Is it bushed? If so, do these bushings wear out as well? If so where do we get them?

TKRIV Posted September 5, 2020 Share Posted September 5, 2020 Lots of us down here in Australia have ordered rear bushing form lots of vendors and have been told that what is offered is a direct or near direct replacement bush. Not so. In some cases we have had road worthy compliance rejected as it's obvious that the bush replacement is not as per OEM. So we have to spend big $$$ to get them custom made. Some of the pricing vendors are asking for non OEM bushes is crazy. Thank you for your feed back. Bushes are for the rear lower control arms (4 Qty) and the rear upper "adjustable" control arm (2 Qty) The upper and lower use the same bushing. They can't be used for the front lower control arm. They are different. Tooling samples that we have been using have been as per 1965 Riv. We make the assumption that bushings are the same for 63 & 64 but this needs to be verified. (it amazes how there are so many small design changes that Buick made between 63, 64 & 65 i.e. door hinges) Yes the bushes will most likely be shipped in bulk over to the USA and offered to a vendor(s) to reduce S&H but we have yet to figure that out.

TKRIV Posted September 10, 2020 Share Posted September 10, 2020 The first lot of bushings should arrive late next week which will be used for destructive testing. Will let you know how they perform. Can anybody verify that the the bushings for 65 are the same as 63 & 64? (USA vendors offer the same bushing across all there years) The 3 of us involved with this project all own 65 Rivs. With the COVID lockdown we are not allowed to travel more than 5km from home!

TKRIV Posted September 11, 2020 Share Posted September 11, 2020 Destructive testing. Fit and check for dimensional tolerance to lower control arm. Check for bonding of the body to the rubber core by rotational flexing at ambient temperature until fail. Repeat at high & sub zero temperatures. Check lateral stability. Compression, impact & fatigue tests. Chemical resistance. So it will be anything that that we can test for chemical, thermal, dynamic & static analysis.

Until then (and you might have this already): · As I understand it, below are the part numbers. Is there a cross reference list from year to yearsomewhere? There isn’t any number for the bushing separately (as expected). 1965 Riviera From the BUICK CHASSIS AND BODY ILLUSTRATION AND GENERAL INFORMATION CATALOG MODELS 1940 TO 1970 INCLUSIVE that I downloaded from Eric Schmid’s website, thank you. · 5.382, 1371358, Upper Control Arm and Bushing, Inner. · 5.382, 1371359, Upper Control Arm and Bushing, outer. · 5.382, 1371356-7, Lower Control Arm and Bushing · 8.900, 9419852, Bolt upper bushing, the same for the lower bushing Note that only the 1965 Riviera rear end is included in the pdf book (page 5.9) and there seems to not be any gaps, maybe that is an indication that it is the same for 63-64??? 1963 Riviera (from Jim Cannon’s 1963 Buick Chassis and Body Parts Book, highly recommended to buy) · 5.382, 1358171, Upper Control Arm and Bushing, Inner. · 5.382, 1358172 , Upper Control Arm and Bushing, outer. · 5.382,1361639 , Lower Control Arm and Bushing Left · 5.382, 1361638 , Lower Control Arm and Bushing Right · 5.382, 1362139, Bolt (the same bolt everywhere as for 1965).

XframeFX Posted September 15, 2020 Share Posted September 15, 2020 Andrew, Thanks Yes, for a couple of years now, I try to convince Vendors to ship via USPS which Canada Post brings to my door. Zero Hassles! Couriers don't get it. They think the market is to have it in your hands the next day. It took 2-weeks for the last order thru USPS 1st Class and didn't get ripped-off. However, if a vendor refuses USPS, I choose either FEDEX Intn'l Express or UPS Int'l Priority where those services include brokerage making it 1 less fee. I also ship to the Authorized FEDEX location at the airport, now 2 less fees. For on the Commercial Invoice to Canada: "Antique Auto Parts - Harmonized Code 9966.00.00" My kid who lives away still uses our home for his project parts shipments. He doesn't listen and lets the vendor ship their preferred way. The Courier dude is laughing with all the charges COD! 1 Link to comment Share on other sites More sharing options...
psychostang Posted September 15, 2020 Share Posted September 15, 2020 I found this out, years ago, when I was selling two used tires. The guy from Canada told me to ship via USPS, also to ship them open. He said they would fly thru customs, with no broker fee because of USPS. I looked funny walking into USPS with two tires!..l.:) 1 Link to comment Share on other sites More sharing options...
