Last fall I replaced my rear yoke and trailing arm bushings . Now with 410 miles on them the large

  rear trailing arm bushings are done . I contacted Rare Parts the maker and they were defensive and

  wanted me to purchase new ones and if sent the old ones back they,  upon inspection would  reimburse the original seller  (Old Parts) a seller on ebay. Seemed like a lot of hoops to jump through so I inquired at all the

known Cadillac Suppliers and it seems the Rare Parts is the only maker of the RP15606 bushings . Further

 internet searches found this is a common problem. This has led to Dan McNarry and Russ Austin heading up making replacement arms with high tech bushings that do not distort and last. Rare Parts needs to retool and use rubber that will last .  In the mean time DO NOT  purchase trailing arm bushings from them with the

expectation they will last as I assure you they will fail quickly

I asked the same question that you did about putting the poly bushings ( like are on Dans arms ) and Russ came back with they are not available in the correct sizes for our stock arms
Jeff came back with --poly bushings will make the car drive like a garbage truck from his research
So both those issues leave us with no reasonable bushing replacements available
Those issues are covered in the prior posts in this thread
Hope that helps

Between a serious bushing replacement and drive shaft vibration issues ( others have ) our drive train have litle chance of being as good as they were when the car was new For the long haul
This is not GOOD news !!

I have no issues with my own car ever regarding the above but i sure would like to know we have a light at the end of the tunnel regarding the bushing issue

Any chance the stock arms could be machined( by a shop ) to accept another size poly bushing if that is the only type avaiable that is durable enough to hold up for a reasonable correct time
We may have to live with a harder squeeky ride it appears if that can be done


This might be a very good subject to be bringing up at the CLC --to see how those boys have addressed this issue over the years


Tony, Can you check around to see if someone can revulcanize the original bushings if someone sends them a core. Perhaps you can contact Steele Rubber? Let us know what you find out. As far as the CLC most members of the forums are non-members so please post your question and give us the feedback. Here is the link: 


Maybe you didn’t see it but I did some research on an earlier message and found a manufacturer in Georgia, USA who makes these types of suspension bushings with rubber. 

Perhaps you could furnish a sample to them and they could match it up and quote us a price. 

When you get back of course. 

Here’s the info:

I saw the post. I don’t need control links or bushings, but if I did I would check with someone like Steele that is well known for revulcanizing rubber mounts and see if they can work with sleeve bushings? I don’t know but does not hurt to ask and unlike trying to match up a metric size bushing, you will probably get a quick yes or no answer. Let me know what you find out.

I will speak with steele rubber products on Mon
They are closed



Just spoke with Steele Rubber Products 

Shay at extension 3217

1800-447 0849  ( 8-6pm m-f )

Pls call here and she will email you a form to be filled out so you can send her a rear control arm core  to consider 

They will take about 2-3 weeks to let you know if they  are interested in making that revulcanized  part that we need  so badly for our rear end control arms 

We know there is a definite need for a product that can hold up for more than 400-600 miles like the only parts available now 

Looks like there could be a light at the end of the tunnel regarding the issue 

That’s the scoop so let us know how it all goes

Looks like there is a serious need for the product and hope they see it that way 

Great idea of yours to be contacting them on this subject 

Fingers crossed !!!


Sounds good, Tony. Sort of thought they might be able to do something.  So, if Jeff, Doug or someone wants to send them their control link with bad bushing they may have a better solution. The only thing I would question is why couldn't someone just send the old bushing? 


Shay at Steele was only asking to send the bushing ( bushing core ) not the complete trailing arm



Is the rear end yoke something else we should be looking into being revulcanized while we are looking into the  rear control arm bushings being done ?

Nothing like —a tight Rear End -the way I see it —LOL !


I am sure there may be other areas where someone like Steele could fill a void where there are no other options.  

Just to add, I have no knowledge of the availability of the upper control yoke bushings or the extent to their reliability. If I needed one, I would use google, and poll the troops here on the reliability of sourced bushings. If they were also crap material I would then pursue someone like steel to install new quality rubber. Again, a great project for you guys with "bushing issues"!

Caddy Daddy has all of the rear suspension bushings and ball joint individually or as a kit 

And provides the dimensions:

1963 series 62 convertible transmission issue

Posted by Matthew VanDeWater on June 22, 2021 at 3:03pm 1 Comment

Hello I've been restoring a 63 for way to many years. Down to almost done, but have issue with trans linkage, when column in park shift rod 2 inches short. everything original. been trying to find picture of manual rod hooked up from under car to see position of linkage. was wondering if anybody has access for pictures. I wanted to see if my manual linkage is bent  wrong out of the trans if somebody dropped the trans or something. Doesn't make sense why it doesn't work. Thanks for any input…

Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…


Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…
