The best drive shaft yoke seal is the one that matches your vehicle and the specific output or pinion location that is leaking. The GM Genuine Parts seals are aimed at GM applications, while the Omix-Ada seal is specified for certain Jeep models with an NP231 transfer case. USA Standard Gear offers a transfer-case output yoke seal, and the Mopar option is a differential pinion seal rather than a transfer-case yoke seal. Confirm fitment and seal location before ordering.

GM Genuine Parts 8673526 Front Seal
This GM Genuine Parts front slip-yoke oil seal is best for buyers replacing the corresponding seal on a compatible GM vehicle. Its stated purpose is to replace a GM vehicle’s original factory component, and it is manufactured to GM OE specifications for fit, form, and function.
Choose this seal when the vehicle’s parts information identifies 8673526 or 08673526 as the correct front slip-yoke seal. The OE-spec design is the reason to consider it over a generic part when maintaining the original GM application. The supplied details do not list vehicle models or years, so confirm exact fitment before ordering.
GM Genuine Parts 52058730 Rear Seal
The GM 52058730 is best for a GM vehicle that calls for this rear drive shaft slip-yoke seal. GM states that the part is designed, engineered, and tested for GM vehicles and provides a precise fit for easier installation.
Choose this part when its number matches the rear seal specified for your vehicle. The product information recommends professional installation through a GM dealer, independent service center, or body shop. The listing does not provide a complete model-year fitment list, so verify the application rather than relying on the brand alone.
USA Standard Transfer Case Yoke Seal
This USA Standard Gear product is best for a buyer seeking a rubber yoke seal for a transfer-case output shaft. The listed features identify it as a transfer-case output shaft rubber yoke seal and describe the brand’s chromoly axles as suitable for street and off-road use. That axle information does not establish the seal’s vehicle fitment.
Choose this seal only after confirming that its dimensions and application match the transfer case. The supplied product details do not specify vehicle models, years, or seal dimensions, which makes fitment verification especially important.
Omix-Ada 18676.29 NP231 Rear Seal
This Omix-Ada rear output yoke seal is best for specified Jeep models equipped with an NP231 transfer case: 1987–1995 Wrangler YJ, 1988–1996 Cherokee XJ, 1987–1992 Comanche MJ, and 1993–1995 Grand Cherokee ZJ. The product is sold individually and is described as a direct replacement.
The listed dimensions are 2.383 inches outside diameter, 1.503 inches inside diameter, and 0.42 inch wide. These details help buyers compare the seal with the part being replaced. Avoid choosing it based on Jeep model name alone; the NP231 requirement and year range matter. The related rear extension housing output bushing is a separate part.
Mopar 68003265AA Differential Pinion Seal
This genuine Mopar part is best for buyers whose vehicle-specific parts information calls for differential pinion seal 68003265AA. It is included as a related driveline sealing option, but it is not identified as a transfer-case output or slip-yoke seal. The distinction matters because seals at different driveline locations are not interchangeable by name alone.
Choose this product only when the required component is the differential pinion seal and the part number matches. The supplied details do not list supported vehicles, dimensions, or installation guidance, so confirm the vehicle application before purchase.
Buying Guide: How To Choose A Drive Shaft Yoke Seal
Is the leak at the transfer case or differential?
Identify where the seal sits before selecting a replacement. A transfer-case output yoke seal, a front or rear slip-yoke seal, and a differential pinion seal serve different locations. A product described as a pinion seal should not be treated as a yoke seal unless vehicle-specific parts information confirms that it is correct for the repair.
How do I verify vehicle fitment?
Use the year, make, model, engine, trim, drivetrain, and transfer-case or axle information when available. Match the part number against a reliable vehicle parts catalog or the original seal. For the Omix-Ada option, verify both the listed Jeep year range and the NP231 transfer case. For products without a published application list, do not assume compatibility.
Should I choose an OE-branded or replacement part?
GM Genuine Parts products are described as GM OE-spec replacements for specified GM applications. The Omix-Ada listing provides specific Jeep fitment and dimensions. USA Standard’s supplied details identify the seal type but do not provide vehicle applications. Compare the available fitment evidence rather than choosing by brand name alone.
What details should I compare before ordering?
- Part number and seal location, such as front slip yoke, rear slip yoke, transfer-case output, or differential pinion.
- Vehicle and drivetrain fitment, including transfer-case type when relevant.
- Seal dimensions when listed, and measurements from the old seal when appropriate.
- Whether the repair requires a seal only or a separate bushing or other component.
Frequently Asked Questions
Are all drive shaft yoke seals interchangeable?
No. Seal dimensions, location, and vehicle application differ. Match the replacement to the specific driveline component and vehicle.
Can I use a differential pinion seal as a transfer-case yoke seal?
Not unless vehicle-specific parts information confirms the same part is correct. These names refer to different sealing locations.
Which listed seal has the clearest Jeep fitment?
The Omix-Ada 18676.29 lists specific Jeep models and years equipped with an NP231 transfer case, along with seal dimensions.
What if the product listing does not show my vehicle?
Verify the part number through a vehicle-specific catalog or a qualified parts professional before ordering. Do not infer fitment from a similar model or brand.
Does the GM 52058730 include installation instructions?
The supplied details recommend having the part installed by a GM dealer, independent service center, or body shop; they do not provide step-by-step instructions.
