I NEED HELP!! As most of you know, Tuners Nation has gone out of business, and now no-one is making the 1g subframe bushings. I plan to make them myself, but have been held up because my lathe is down, and the cost of repairs are more than the machine is worth, so I need to get my turning done elsewehere now.
In any case, I made the HUGE mistake of selling my LAST set of 1g subframe bushings, and now have no sample to take measurements from. Does ANYONE have a set of these that they have not installed yet that they would be willing to lend me for R&D?

Just an update...this is becoming a bit of a nightmare. I had several pieces cast, but the bore did not shrink as expected!
It looks like these first pieces might all be scrap, unless I provided a different metal sleeve to press in instead of using the original.....
Does anyone have an old "crossmember bracket" kicking around? It is the sort of oval shaped piece with the protrusion that fits into the bottom of the subframe bushing. Also, if you had the nut, it would confirm for me the bolt size, in case I DO decide to source different metal sleeves. Even better would be if you had the old bushing complete with the metal sleeve that I could borrow.
Reza, please let me know if you need these back soon, this is taking a log longer than expected...

Thanks Reza, I appreciate that.
I have spoken with my urethane guy, and so far he doesn't even believe what I am telling him, LOL. I will meet with him in the next few days, and should know a lot more then.
In the meantime, I have two options here, and I am looking for some feedback:
1. If my urethane guy can assure me that they will ALWAYS react the same way as this first batch, I can just have new cores made the correct size, and have a fresh batch poured.
2. The other option would be for me to source some metal busings, and have them installed in the mould and the urethane cast around them. This would eliminate the need for re-using the metal sleeve from the old bushings, but it would add to the cost.
Would love some feedback, and still looking for those samples as mentioned above...
Thanks

Jeremy, I might eventually look at doing 2g bushings, so your input counts also.
Mike, I am pretty familiar with mould work and shrinkage, but in this case the ID has hardly shrunk while the OD and length shrunk as expected. I wonder if maybe he let them cool on the cores too long before removing the cores?
Either way, it shouldn't matter.....as long as he can give me consistency...and if I DO end up going the route of having the new sleeves cast right into the bushing, it won't matter one bit.

I would buy them with new sleeves. I hate rusty sleeves or having to source things from many places.

Ok, that is the opinion I wanted to hear...and that brings to mind the next question. I understand that the bushing must be tight in the subframe, and the sleeve must be tight in the bushing. Here's the thing: With the bushing being urethane, not metal, it "gives" some. When the sleeve is pushed in, it actually "expands" some...so that has me wondering...the current "Tuners Nation" bushings....is the bushing installed in the subframe first, and then the installation of the sleeve in the centre tightens it into place? Or is the sleeve installed first, then the entire assembly pushed into place? I guess I am wondering, if I make them with the sleeve already installed, do I need to make the outside slightly larger, to make up for what it would have expanded when pushing the old sleeve in?
I really wish I had an old bushing, an old sleeve, and ideally even a subframe (or part of it at least) to play with. Anyone scrapping a 1g AWD?

Thanks, but no, I have Reza's here. I am questioning how much they "grow" when the sleeve is pushed in. We are planning to make these WITH new sleeves, and have a couple of options: We can just make the outside same as now, and provide the sleeves to be pressed in after installing the bushing, or we can cast the sleeve right into the bushing, but then we would probably need to make the outside of the bushing slightly larger to account for the lack of growth when installing a sleeve

After consulting with a few people, we seem to have reached a decision. We are going to SUPPLY new sleeves with them, but not have them cast in. The process of installing the sleeve AFTER the bushing is installed actally TIGHTENS the fit of the bushing. We have ordered material to make the sleeves from, and are now just waiting to get an actual measurment of the new sleeve, then we will calculate size and turn new cores for the existing molds. So, we are still several weeks away,but getting closer......

Are sleeves available new OEM or just a whole bushing? Or neither?
