I have a 1992 Loyale SW. The bushing at the top of the rear differential has fallen apart.  I looked on line and called Subaru but the bushing has been discontinued.  Does anyone know where I could find one?  

Used.

 

Ebay.

Craigslist

Post in the parts wanted forum here

Look for a way to make your own bushing.

Make your own with urethane.

 

SuperPro might have some EA bushings.... still easier to get some smooth-on two part urethane and make a cardboard form. LOTS of YouTube videos on the process.

do you know how robust it is compared to OEM materials?

 

And what’s the learning curve for a noob - on a scale of 1-10 how easy is it to get a good fit and alignment?

someone could turn one out of what? nylon or one of the many plastics available. Shees, an old cotton reel for starters

Thanks for the suggestions.  I will check out Super Pro.  Has anyone out there made one?

Do you know where I can find a good schematic of the rear differential? I should have taken some pictures while it was up on the rack  

Hello? McFly? I said YouTube.... search. Like a million videos on this.

schemtaic is not what you need is it - stil talking bush ?

 

You most likely need to know if the original that is likely fitted, if it has an external metal sleeve that needs to be knocked out or burnt out with the rubber bush,

 

how wide the bush can be min or max, bolt hole size and bush outer diameter

 

are you that remote that the Indians from India have not infiltrated workshops your area with popular common rubber bushings ?

 

See a workshop that deals in suspension or differentials, they may have the answer on the shelf, the press to get old out, new in

get prepared for lots of stuff that is dizcontnued for a car that stopped production a third of a century ago

Just buy a tube of 3M Window Weld, tape up one side of the factory bushing and fill in the voids in the bushing with the 3M product.

That stuff isn't nearly resilient enough. The two part products by smooth-on are a much better option.

GD, I'm going to disagree with you here.  I've used this stuff on two cars so far, one of which was my T-wagon 4 or so years ago.

 

I picked up this trick from Dave Coleman, current design engineer at Mazda R&D.  If it's good enough for his championship rally cars, it's good enough for our differential outrigger bushings.

 

Now, that said, I'm not suggesting that a new bushing be made from this material, just that a failed bushing could be refreshed by filing the voids with 3M Window Weld.

As far as filling voids in old bushings, yeah it will do OK with that. I've used it and I wasn't terribly impressed by it.

 

But for making completely new bushings it's not liquid enough to flow and doesn't have the right durometer - you can also get the smooth-on stuff in any durometer you like. It flows out to provide a really nice finished look if you do it right using a vacuum chamber (you can make one) to pull out all the air pockets from mixing.

Ive made a few bushings ive used rtv ultra black silicone before also tire black rubber tire repair to make bushings and rebuild tire sidewalls on off road racing tires when i worked for goodyear tires also old tires can be used for bushings i do that alot too ive made suspention bushings out of old tires and had them hold good 5he best though is the urithane its cheap easy to work with and outlasts any rubber bushing also they look good lol thats whats realy important right lol the urathain is the way to go i got a 10 pack of urithain bushings on ebay for like $10 when i started to built my long arm kit for my loyale you can get it in just about any size you need i would order the size of the outer diamiter and drill the center out to fit your pin or use 2.bushings one inside the other one thing though if you replace the bushing on the diff with urithane you should also change the bushings on the mustash bar aswell if you just shore up your current bushing with liquid rubber of some sort you probably dont need to mess the mustash bar bushings  all the diff bushings should be the same material or else you risk breaking something else not that these rigs realy have enuff power to break stuff but its a posability

How about going to harbor freight, spend $350 on a lathe, and make a bushing right and use delrin or poly Of you do that I'll chip $75 for my set, that's 30% of the lathe! Inject and fix old s GD suggested, or spend the dough, make them right and make all your soon to be paying customers happy!

derlin is to hard it wont allow for any flex at all might as well just weld it solid at that point the polyurithane has just a little bit of give thats why they use it for replacement performance bushings and you can get just about any size you want because they make replacement bushings for just about averything mine were for a datsun or something i just had to adjust the center hole size but polyurithane is very easy to work with you dont need a laith more than likely you will find the size you need just search by the size and not the vehicle and if you cant find the exsact size look for the od you need you also might have to trim them down width wise a simple hack saw cuts it very easy it drills easy if the center hole is to big sleave it with some kind of pipe its not a big deal dont over think it it just absorbs shock and twist loads so you dont feel them in the car even if you did weld it solid i dought you would be able to tell the differance in the long run the metal might fatiuge faster but urithain is the way to go best of bothworlds stiff but still flexable
