Rear Wheel Bearing & Seal Kit | Honda CB350 / CB360
Wheel bearings are what let your Honda's rear wheel spin smooth and true, and they are one of the most overlooked parts on these bikes — most are still riding on whatever the previous owner left in the hub. This kit covers the rear drum-brake hub on the CB350 / CL350 / SL350 K0 and the CB360 / CL360 / CJ360 with top quality European made bearings and a fresh dust seal.
Why You Need This
Worn rear wheel bearings let the wheel develop play and wobble — and it only gets worse the more you ride. If your rear bearings are oozing grease, feel crunchy when you spin the wheel, or show lateral play (back-and-forth movement perpendicular to the axle), it is time to replace them.
These are sealed bearings, not the kind you repack — once they are dry or contaminated, fresh ones are the fix. Our kit pairs the large drive-side bearing with the smaller brake-side bearing and includes the dust seal, with ample grease packing in both.
What's in the Kit
- Drive side (large) rear wheel bearing
- Brake side (small) rear wheel bearing
- Dust seal

SL350 owners: This kit fits the SL350 K0 (1969–1970). The SL350 K1 and K2 (1971–1973) use a different, smaller rear drum and are not covered here.
Note: The bearing retainer itself is not part of this kit. If yours gets chewed up on the way out, grab a replacement retainer (also available as an add-on above).
Installation
Difficulty: Intermediate
- The factory bearing retainer is staked into the hub. Drill the peen marks ever so slightly with a sharp 1/8" drill bit — just past the surface, no deeper — then soak the retainer in penetrating oil.
- Heat the hub with a heat gun to expand the aluminum, then back the retainer out with the retainer tool. Heat is what gets retainers and bearings out without a fight.
- Drive the old bearings out with a long punch or drift worked at an angle on the inner edge — carefully, so you do not damage the hub. A hot hub will often give them up with light taps.
- Toss the new bearings in the freezer for a few hours before the job. Install the bearing on the retainer side first — that side of the hub has a seat lip that sets the depth — and account for every spacer that came out. On the 360 rear hub, one of the spacers rides on the bearing's inner race, so note where each one goes.
- Drive the new bearings in with a large socket or tube just smaller than the bearing's outer race. Do not press on the inner race or the dust covers — that damages the bearing.
- Reinstall the retainer with anti-seize on the threads — it should go mostly by hand once the threads are clean — then stake it in a few places with a center punch so it cannot back out.

Frequently Asked Questions
How do I know my rear wheel bearings are bad?
Grab the rear wheel and rock it side to side: any lateral play means worn bearings. Oozing grease, a crunchy feel when you spin the wheel, or a wobble that grows with speed are the other tells.
Do I need the retainer tool?
Strongly recommended. The factory retainer is staked into the hub and usually takes drilling, penetrating oil, and heat to let go — improvised tools tend to gall the retainer holes. The retainer tool seats squarely and works for both removal and reinstall.
Is the retainer included in this kit?
No — the kit is the two bearings and the dust seal. Retainers are available as an add-on above or as a separate part if yours gets damaged on removal.
Will this fit my SL350?
It fits the SL350 K0 (1969–1970). The SL350 K1 and K2 (1971–1973) switched to a different, smaller rear drum, so this kit does not cover them.
Will this fit my CB450, CB500, or CB550?
No — those bikes use larger rear bearings. Use the CB450 / CB500 / CB550 rear wheel bearing kit instead.
What else should I do while the wheel is off?
Inspect the rear brake. New shoes are cheap insurance while everything is apart: CB350 / CL350 / SL350 shoes or CB360 / CL360 / CJ360 shoes.
