After the long months of stripping, painting and reassembling the car, I had high hopes for getting around in it for a bit. Alas, it was not to be.
I had previously replaced the rear wheel bearings as part of the initial restoration, and I guess I should have expected that the front bearings would retire at some point too. For a long time before the teardown I had lived with a slight rotational sound audible only at low speed, but figured it was not of any concern since it wasn’t getting worse. As it turns out, while standing around for a few months in my garage, the bearings had apparently deteriorated somehow. It was now making grinding noises under braking and the wheels were tram-tracking like crazy on bumpy surfaces. The former probably only became apparent after I had replaced both the front rotors and pads during the reassembly, the latter I had ascribed to the Konis and poly-bushes, but it was worse now and pretty disconcerting. So I pulled off the front brake and hub assemblies, after I acquired a 2 meter piece of pipe, and found grease all over the one dust cap with both bearings having sideways play in excess of 2 to 3 millimeters, which would explain the instability of the front wheels.
So then I had to get hold of new bearings. This front-hub and bearing assembly is considered a unit, and Mazda doesn’t have a separate part number for only the bearing. The EPC only details the entire hub as a single part. So of course the dealer price per hub was around R4500.00, where-as I could get aftermarket parts from both the UK and Dubai for less than R1000.00 and R500.00 respectively. So I ordered and waited.
While waiting for the parts I got another set of stands and lifted the rear of the car off the ground so that I could also adjust the handbrake. This has never worked properly before, but it’s a simple process involving a small adjustment screw on either side. With that done, and the hubs finally here, I “piped” everything back together again in no time, and the results are...dramatic. The front-end feels way more solid and composed now, with the turn-in response better than it has ever been. I’m really happy now, and bearing life is something I will always consider and inspect whenever I buy another older car.
Can you still read a wiring diagram from school? I tried. Also had the car out on a back road for the first time in almost 6 months.
The project suffered some setbacks, one which is pretty big and commands even more unforeseen expenses to correct.
The last month or so saw some serious work towards completing the car's interior, including sealing and sound proofing. Finally I'm on the home stretch to complete this restoration!
