Bearings, Seals, and Maintenance Parts Matrix for R50 R200A and H233B Axles/Differentials

[hawairish]

Twelve years of owning an R50, and almost 28 years owning and working on Nissan trucks (and cars, briefly)...and I'm just now getting around to putting together something like this.  Still seems like people are trying to keep these trucks on the road, so hopefully this helps.

 

This is a current matrix of maintenance and service parts for the R200A and H233B axles/differentials found in R50 Pathfinders and JR50 QX4.  It covers all basic parts like seals and bearings, providing the current Nissan part number, superseded part numbers, quantity used, and a few suitable aftermarket part numbers.  It also indicates which parts are No Longer Available ("NLA") from Nissan; they might still be available from international brokers and suppliers like Amayama.com and Partsouq.com.

 

This list (particularly the aftermarket part numbers) is not comprehensive, but should be a good starting point; nearly all of the parts listed have a confirmed cross-reference to the OE part, some I've personally used.  RockAuto's part number search DOES search across interchange numbers listed on parts; enter the OE part number without hyphens (i.e., "3818921G17").  There are definitely other parts that will work, especially more-affordable options; compare the specs of a listed part to other parts.

 

It does not include any differential parts, LSD parts, or parts that would be needed to set up gears like shims and spacers...the majority of those parts are completely unavailable.  The best option if wanting to change gears is to source a complete 3rd member or entire front differential from a donor vehicle, and service it using the parts from this matrix.  Due to the nature of the high-pinion R200A we have, there are NO aftermarket gears available for it.

 

Again, this is SPECIFICALLY for R50 trucks only.  Other R200A front differentials (like those from W/D21, W/D22) do use some of these parts, but not all.  The H233B data is for 33-spline only.  Again, some parts do interchange, but some do not (mainly the inner seals and outer bearings which are sized smaller for 31-spline shafts).

 

Keep in mind replacing many of these parts requires access to specialty tools, like pullers and a floor press, to disassemble and/or assemble components.  Most of these parts cannot be bashed off, and some rental tools at your local auto parts store may be insufficient.  A clamshell-style bearing puller like this works great for pulling pinion and carrier bearings.

 

The matrix likely applies to foreign Terrano and Regulus models, too, but do your homework because you know Nissan did some really dumb things with these trucks.

!	INSTALLATION NOTES
A	Axle shafts must be COMPLETELY disassembled (ABS tone ring, bearings, bearing cup, etc.) in order to replace the outer axle seals. This process requires a suitable tool and/or press. These seals are mainly grease-catchers for the bearings. However, if the inner seal is leaking gear oil, it likely has compromised the bearing grease. Axle shaft tear-down is recommended to regrease the wheel bearings and replace the seals.
B	Replace the RH outer shaft seal, outer bearing, and bearing collar together. The bearing shaft collar MUST be destroyed-off with a cold chisel BEFORE the bearing can be removed, and before the seal can be replaced. Attempting to pull the side shaft with the collar installed WILL destroy the flange plate (38232-01W00) and bolts.  Ask me how I know.  The "RW114R" kits all include a bearing and new bearing collar; the seal is sold separately. A slide hammer is needed to pull the shaft from the bearing, and a press is required to install the bearing and bearing collar on the shaft.
C	The axle shafts must be completely removed from the axle in order to replace the inner shaft seals and outer o-rings located at the ends of the axle tubes. This requires disconnecting the parking brake and hydraulic brake lines from the drums. The axle shafts will rest on seals, and potentially damage them, when the axles shafts are only partially pulled from the differential. FSM says to remove the ABS sensors from the axle tube to avoid damaging them when pulling the axle shafts.
D	The R50 Pathfinder uses a 9-bolt R200A differential only found in E50 and E51 platforms. All other R200A, R200, and C200 differentials found in other Nissan trucks and cars have 8-bolt covers. There are NO aftermarket gasket options for the 9-bolt differential.

Excellent work, always appreciate the detail in your posts! Many of these parts probably translate to the WD21 as well, but I haven't verified yet.

Thanks!  Yes, definitely a few W/D21 and even W/D22 compatibility (100% for their H233B).
