Prothane 12-1601 Differential Bushing Set

Complete and a good fit. Eliminated the rear end clunk noise on my 200,000 + mile NB1 Miata.

Fit PERFECTLY for diff swap to a ‘99 1.8 diff on my ‘93 miata. Description did not make it obvious that it would work, but if you are replacing your 1.6 diff to a 1.8 -this is EXACTLY what you need.

I advise you to have the tools and knowledge to improvise to install these solid bushings. This is not easy and as you may find yourself hurting your self or damaging the rear end, CV shafts, brakes, seals, etc. Do you have a press, good floor jack, plenty of degreaser, Ive this on two occasions and it took a lot of time and patience. It is not the bushings that are the problems, it is the removal of all the stock components keep up with everything!

I used these during the install of a torsen differential in my miata since my poor 1.6L differential had gone to pieces. The install is pretty straight forward, however Im going to knock a star because they do not include or even mention lubricating the bushings. I used some ES hyperlube that a friend had sitting around to make sure that they would not squeak on me. I will say these do add a fair amount of NVH into the car...

Toss your diff plates in a fire pit to melt the rubber off. These are nice bushings.
