At last, we now have in stock replacement polyurethane uprated bushes for the lower mount of standard shocks as fitted to mk2 Mazda MX-5's and Roadsters.
Fits mk2 (NB series) cars, 1998-2005.
Here are a few tips on fitting:
Check the internal diameter of the shock eye is around 34.5 mm.
Then original bush shell remains in the shock eye, and would be a messy job to remove without specially made shouldered drifts, collars and a press.
Therefore we developed our bush to fit with the shell remaining, as it is when the typical failed rubber bush is removed.
It is important to radius the fairly sharp corner in the ID of the shock eye with a round file. This will greatly assist fitting, and prevent damage to the new PU bush.
Lubricate the shock eye, and use a bench vice to squeeze the PU bush into the shock eye. Lubricate the ID of the bush and squeeze in the crush tube, from the end of the bush that didn't pass through the shock eye.
Wriggle the shock with the installed crush tube held tightly in the vice to settle the bush.
