RX-8 Front Wheel Bearing Hubs Timken HA590360 (OEM: F189 33 04X)

Today’s project replacing the stock MX-5 front wheel bearing hubs with an upgraded option: RX-8 front wheel bearing hubs by Timken (part #HA590360 (OEM: F189 33 04X)).

The problem was a weird humming noise after a trip to Detroit, Michigan. I thought that maybe I damaged some suspension component by all the pot holes I hit on those horrible awful roads, but the shocks, springs, and all the tie ends/rods were fine. The noise was especially noticeable when turning right at speed, it would hum differently and louder. But the culprit wasn’t the right bearing it was the left side instead. I replaced both.

Ordered the parts from RockAuto.com who was the cheapest option at $206 bux whereas everyone else was closer to $168+ tax for each. Rock Auto charged no tax and had free delivery which was ultra quick. The parts arrived in one day!

To do the job I had to go to AutoZone to rent some tools. I got a slide hammer and a torque wrench. Unfortunately the torque wrench was broken, so I tightened everything up by feel instead. It was a very straightforward job that took a few hours because I didn’t rush it.

The CRC degreaser worked like magic!

The most difficult part of the whole job was removing the left side brake disk/rotor. It was totally seized onto the hub. Even the two screws holding the disk in place were a major PITA to take off.

Little clean up and new parts were going on with some anti-seize to lube it up and some loctite thread locker on each bolt.

The first and last step of the job was to unbolt the ABS sensor.

Next test drive… feels quieter and much tighter steering. Going to see how it holds up on a thousand mile road trip to VIR next.
