Still in the early stages and I could use some recommendations on differential install kits/parts.
I've got the keystone pieces in the garage as I attempt to collect the ancillary parts before I rip into the car. Planning a 4.3 re-gear with rear only Harrop e-locker. Locker is less of a priority for me as I want to re-gear for heavy towing with 35s. But while I'm in there sort of thing...might as well get a locker in.
My preference is always OEM parts where possible, versus aftermarket. Sourced the following for their 4.3 ring and pinion gears:
1) '02 LX470 rear differential
2) '12 Tundra (with tow package axle code BO2A) front differential
Questions:
Any lessons learned on parts to refresh replace? I'll likely just source the master re-build kits from Nitro. Can I get away with less, and do I absolutely need everything in the kits? I do want to replace all the carrier bearings and seals. I think I might have enough shims between the 4 diffs on hand, and a few other pieces?
LC200 rear axle bearings have been known to need replacement in higher mileage. As I tow near GCWR, probably a good time while I'm in there right. Anyone have a parts list here? Seals?

Front Diff
- 4.3 carrier from Tundra or Sequoia. Probably 08-20?*. 4.3s only came on these models with the optional tow package. Look for door sticker axle code B02A. Parts resellers should have the associated VIN which you can check on Toyota website to confirm tow package in options list.
*I don't know that there were absolutely no changes through 2020 that affect fitment on the 200-series. Mine is from a Tundra 2012 that fit fine.
- Fitting a locker to a front clamshell carrier is supposedly no joke with need for special measuring tools for lash. Fortunately if not looking for a locked front axle, it otherwise drops in after changing out the peripheral ADD actuator
- I sourced mine for $175 shipped
Rear Diff
- 4.3 carrier from 98-02 LC or LX. This ratio came from the 4-speed cruisers of the day (03+ got 5-speeds)
- There are factory locked ones available. Comments suggest this could be retrofitted for air actuation. For LX models only that won't have sway bar interference against the actuator.
- Carrier is directly drop into the 200-series
- Note that the 100-series uses a smaller diameter input flange and snout on the pinion shaft. If you're just looking to source the ring and pinion with full size snout, and will rebuild from your current diff, @bloc was able to sleuth a new OEM R&P 4.3 parts kit ( 41201-80493 )
- I sourced mine for $120; $200 shipped
