need replacement bushings
 

trying to find replacements for the rear knuckle bushings and little rubber dust caps. I know Mazdatrix sells the DTSS delrin bushings. Can anyone help?

buy the DTSS bushings..
Mazda wants you to buy the whole freakin assembly( money grabbin bastards!)..that goes for around 400 per assembly.
Get the DTSS's and take the Rubber out of the Spindle assembly,then grind/chisel the Race out.and install the DTSS's..(Mazdatrix may have a Video tutorial on this)
it is a Bitch,but it is a Good improvement over Crappy 20 year old rubber bushings.

ill be making 80% of th ebushings you need...pay for materials for 2 sets and ill make them for you on the lathe

Get the bushings from MMR-Direct

Do either Mazdatrix or MMR-Direct include the two rubber end caps for either of their sets, or do their sets make the end caps necessary?

All 3 of the rear hub joint bushings/bearings are available from Mazdatrix - DTSS emilinator, upper rubber bushing and lower spherical bearing.

Are you going to make the upper hub bushing (the rubber one) out of delrin?

This may help considerably:

most likely ill be doing it out of solid aluminum....but once i get to engineering my set of bushings ill use the materials i feel will be used best...delrin or aluminum

thanks a bunch Aaron, I have spent a lot of time looking over shit, but that thread is by far the most helpful.
