Title: Rear sway bar link bushing is hard to find!
Post by: attkrlufy on April 29, 2011, 12:44:57 PM
When last I posted I was on the hunt for F & R sway bars assembly bushings.  I was able to find replacement poly bushings for everything except for the center bushing on the rear sway bar link:

It's got a 19mm (3/4") hole and measures approx 1 5/8" L & W.  It's about 1 1/2" thick.  The part that's contained within the bracket is thinner/smaller - about 1 3/8" L & W and 1" thick.

I was hoping to find this in polyurethane, but at this point I'll settle for rubber.  If I can't find it soon, I'm thinking of going to a machine shop and having a new link fabricated that will accept a generic poly bushing and clamp.  Since that'll be really $$$$, I'm hoping to try this one last time with you guys.

Any leads/ideas?

Did you try Justsupension?  They have all sorts of bushings.  You have to call them though.  Have your measurements handy too

That's right, go with the size/dimensions vice application. If I could find kinpins for ah 39 Nash using dimensions vice application, chances are you can find the ones you need. Remember, if the inside hole dimension isn't correct, you can always redill the center, and if the outside dimension is larger, they can always be cut down to fit within the housing, smaller outside dimension can always be filled with metal spacers on the out side within the housing. Gotta do what you can.

I have a similar link on my '70 front sway bar.  I was able to get the bushing, but had to cut out the old one, as well as the weld on that bracket to put it on.  I drilled holes into the bracket before I cut it so that I could line them back up with bolts.  I cut right done the weld center with a grinder wheel.  Actually, with 6 of them - that metal is tough!  It did/does the job.

Yeah, I had to take it to a machine shop to drill out the fusion weld and split the top and bottom brackets.  I don't have the set-up for something like that now that my air-compressor is broken.  But at least I'll be able to service the link from here on.

I did look at their website earlier when I was trying Energy Suspensions, FirmFeel, Kanter, and all the other usual suspects, but I didn't see anything listed from them after typing in my car's make, model, and year in their online catalog.  Maybe they have a "hidden room in the back" online, I dunno, but I'll try them again.  Thanks.

Try the application again-but try using a 79 Cordoba.
An R is simply a stretched B...It is worth a shot since so many Cordoba's and Magnums came with the rear sway bar option.

Well, after combing through catalogs and other mfgs websites, I've concluded that no one makes those square bushings anymore. 

However, there is an extortionist on ebay that has EXACTLY what I need:

http://cgi.ebay.com/ebaymotors/NOS-Mopar-1971-74-B-Body-Rear-Sway-Bar-Bushings-_W0QQcmdZViewItemQQ_trkparmsZalgoQ3dLVIQ26ituQ3dUCIQ26otnQ3d3Q26poQ3dLVIQ26psQ3d63Q26clkidQ3d8826003409895150775QQ_trksidZp5197Q2em7QQitemZ220768010906 (http://cgi.ebay.com/ebaymotors/NOS-Mopar-1971-74-B-Body-Rear-Sway-Bar-Bushings-_W0QQcmdZViewItemQQ_trkparmsZalgoQ3dLVIQ26ituQ3dUCIQ26otnQ3d3Q26poQ3dLVIQ26psQ3d63Q26clkidQ3d8826003409895150775QQ_trksidZp5197Q2em7QQitemZ220768010906)

But $75 + $8 S/H??  I don't care if it is NOS - that's nuts.  It's not even poly....

So I have two options:  Modify the factory rear sway bar link by cutting off the bracket and welding a flat piece of metal w/ 2 blot holes to the shaft so I can accommodate a generic 3/4" bushing like this (minus the zerk fitting):

http://cgi.ebay.com/ebaymotors/Universal-Sway-Bar-Bushings-3-4-19mm-95106-9-5106-_W0QQcmdZViewItemQQhashZitem1dae22352QQitemZ7967220562QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories (http://cgi.ebay.com/ebaymotors/Universal-Sway-Bar-Bushings-3-4-19mm-95106-9-5106-_W0QQcmdZViewItemQQhashZitem1dae22352QQitemZ7967220562QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories)

Or cave in and buy the $75 bushing set.

I'm inclined to modify the link to accept the universal bushing.  It'll be more $$ upfront, but at least the link will be servicable from now on.

You have to call them.  Talk to Luke.  Tell Him Steve Hobby sent you.  He has them.  I know he does

Was also my 1st thought seeing these pics, looks very similar to 65-73 C-body front sway bar link bushings....

Kanter. . . .  You have to live near him and know him to understand Scott.  But his 5th wife divorced him, this one lasting the longest.  He's gone under ground since.

Sorry, but both PST and Justsuspension came up blank.  Luke was really nice (thanks for the referral Steve), but he said they sold out of that style a while ago and he doesn't know of anyone that makes it.  PST had a guy look at the images - but they carry the same stuff everyone else carries.  Which means they don't carry that center, square bushing.

McQuay-Norris also used to make that square bushing, too.....but that was ages ago and they don't stock/make it anymore.

The search goes on.....(http://www.moparfins.com/forum/smileys/smiley16.gif) 
.....though I am running out of time.  I may just have to get some custom work done.

Check the size of that square bushing - the shape is similar to the 65-73 C-body swaybar link bushing. So that may interchange.

It's going to take a little manufacturing/welding, but it is time to simply move on and do a replacement fabrication. The center location of the hole is the important part for handling, but, get a poly bushing with the hole size as the important part. Many of them come with a metal housing on them already, all you have to do is cut a piece of 3/16ths plate steel it can bolt onto (so 1.5 inches wide and 3inches long is about the right size, roughly the size of the metal bushing housing), drill bolt holes to attach the bushing to the plate, then using the original length of the center of the bushing hole to thread start, mark the bent part under the bushing of the original and cut it off at the right length, weld the plate to end and bolt the new bushing on. I't a little bit of work, not difficult, but done properly will look like an upgraded bushing, not a fabricated mess. Paint it black and nobody will know it isn't factory. Need rough pictures, I can draw something up to show it better.

Did Luke ask about me?  I haven't called them in a while.  I will soon though, I need to replace the front shocks in the blue diamond WHICH WERE IMPROPERLY INSTALLED. . .   (SNOTTY!)  and I have to get new sway bar link bushings.  One is missing

You assume too much; I did not put the shocks on that car.

He should have a complete link kit though.
Yeah, but they're not the proper diameter and they're only for the front.

This HD front sway bar from the doner 1979 300 is proving to be IMPOSSIBLE to find the right bushing for.  It is 1 1/8" (29mm) in diameter.  All the B-body bushing kits only go up to 15/16" (24mm).  I called a good local suspension shop and inquired about drilling out the bushing center hole.  They said, "We don't like the idea of it - and we've never done it on poly before."  And they have a drill press and I don't - so I don't like the idea of me doing that, either.

Energy DOES have a factory style bushing for a 1 1/8" bar.....but it's for the FMJ Mopars - and their bushings are circular wheras the B-bdy bushings are square w/ a ridge on one end.

I'm about ready to say "Eff it" and do what Dana44 said.  At least I know I can find generic 1 1/8" and 3/4" poly bushings from Energy.

Yeah.  He wanted to know why you skipped town after borrowing $20 from him.  I think he's still pissed.  (http://www.moparfins.com/forum/smileys/smiley2.gif)

Another option could be to fill up the corners of the link with a bit of metal, so the round Energy bushing fits.

I wouldn't even know to drill into something like polyurethane.....

Do you use high speed / low speed?  What style bit?  Do you use lubrication or not?  If so....what kind is best?

This would be an expensive part to screw up while learning how to ream an 11/16" hole into a 1 1/8" one properly.  If I end up off by more than 1/32", I've probably just ruined the bushing.

It would have to be cooled somehow. . .  And at a slower speed.  You need it fast enough to it won't bind, but slow enough it won't over heat it.
 
The Polyurathane bushings will probably hold up better when drilling.  I never tried that.

Poly drills like plastic. Get it held solidly so as not to spin and simply drill it, just like teflon, medium speed and not too hard with the pressure because of how soft it is compared to metal.  It has been done and can be done again. If you can find the square size you can do it easily enough without fear, the square sized would help in the clamping procedure, round works best if put in a lathe and spin it to cut rather than clamping it and drilling it. Don't worry about the outside lip of rubber like the original, you could, after removing the bushing, drill the metal housing and thread it, then put the poly bushing in and dimple the bushing about .050inch and intall a set screw with loctite to keep it from moving. Something simple like that. This isn't a difficult customize to work, just time consuming.
