Front Diff Mount Prototype
 

Finally had a bit of time to work on some development projects. First on the short list was a replacement for the front diff mount seeing as how mine needs replacing.

All in all I'm very happy with the results. The polyurethane bushings were a bit challenging to make due to their relatively small size, but ended up better then I expected. I still need to set up a jig to check the dimensions but it should only take minor tweaking to get it perfect.

One of the largest challenges was to make sure that the mount properly isolated the diff from the subframe. If the mount isn't designed right, then when you accel/decel quickly the mount can clunk. When I get time I'll try to remember to post a cross section of the mount so everyone can see what I'm talking about.

It's still missing some washers and the bolts for the subframe but I don't have anything the right size in stock at the moment.

Beefy!!!

Nice!!

Please let me know when you start selling this. I would love to buy this for my car. Need something strong for drifting.

I'll take one

I'll take one too.

i'll take one tooooo

I'll be at least a few weeks before I can have these in stock and ready to ship. I still need to do test fitments and so stress testing would be nice as well.

And I just dropped my subframe today...

Might be interested in putting this on my time attack FC.
I'll be watching this thread. To see how she holds up.

Subed to this bad boy...too many nightmares of finding new subframes and replacing that damn mount....quality piece sir...hope it makes it to production.

Sign me up for one too, mine is starting to knock too so timing couldnt be more perfect on this. Hope this this quality looking piece makes it into production soon!!

id be interested in this since i already have the bmc stopper from you guys.
should pair well with my suspension setup and the pinion snubber

Damn it i want one!!

Any progressin terms of testing the prototype?

^^bump?

Been swamped catching up on some parts we have started to run low on. My goal for this weekend is to finally get some work done on my FC, which if it goes well includes fitting the prototype finally.

So when will these go in to production?

All of the above!

I will be watching this thread! Ive got literally every bushing bought for my rear emd cept the diff mount.

looks nice but you may want to test it before selling them.

i have seen enough force on the diff nose to shear off the whole thick steel plate mount tab from the subframe. call me skeptical but i see too many wear angles and not enough load bearing surface on the actual mount. i did think the other design would work that was posted up before where the pucks took on direct load instead of transferring it as a torsional load. i just envision it may be rather solid feeling at first but it will wear quickly until the point where the bolts are doing the work and either wear out the aluminum body or shear the bolts off.

hopefully you take no offense, the materials and machining look good.

^I also worry about this design.

The sheering force is always the issue with our stock mount. The bonded rubber was a serious weak point.

I liked that sandwich style that fell through with the AZ guy. It turned the upward force into compression instead of sheering.

No offense taken, and very valid points. These will be tested as much as possible before they make it to production. A part like this is quite challenging to design because not only does it have to function well, it also has to be cost effective to produce. If I was making this for only my car, I'd mill it out of a single large block of aluminum and have bushings on both planes.

I've included a cross section of the mount so everyone can see how the bushings isolate the plates from each other. One of my primary concerns besides durability, is making sure it doesn't "clunk" under heavy loads. I know I'd personally be very angry if I went through the trouble of installing a diff mount, and it made a unpleasant noise every time I launched hard or was on/off the throttle quickly.

i can't wait to see this in production. i literally just minutes ago ordered your poly engine/trans mounts and DTSS bushings off your site. looks like you make good stuff

I'm interested to see the turn out of these!

Thanks. You order will be shipped first thing tomorrow.

Me too :)
