What This Seal Is and Where It Lives
This is a wheel hub oil seal for the drive axle end - sits behind the hub, keeps differential/axle lube in and keeps road grime, water, and brake dust out. 4.766" shaft bore x 6.311" OD is the working spec here, and that's what actually matters, not the brand name molded into the case.
You'll find this size on a good chunk of drive axles across the heavy-duty truck world - Class 8 tractors, some straight trucks, certain trailer axles depending on the axle manufacturer. It's a common enough size that a lot of different OE and axle-builder part numbers land on the exact same seal.
Bad one shows up as oil on the inside of your wheel, oil-soaked brake linings, or a slow weep at the hub that gets worse with heat cycling. Ignore it long enough and you're paying for shoes or pads too.
Reading the Cross-Reference Numbers
Seals like this get relabeled by whoever's selling them - Alliance, various aftermarket packagers, axle OEMs - but if the bore and OD match, the seal underneath is doing the same job. That's why you see 47691, the 309/392/393 series numbers, and the 370001A/380001A numbers all pointing at the same physical part. Different box, same dimensions.
What actually needs checking before you order: bore diameter and OD have to match your old seal exactly - don't eyeball it, measure it or read the number stamped on the seal case. Lip design (single vs double lip) and material can vary between listed crosses even at the same size, so if your application runs hotter or has more contamination exposure, that's worth asking about.
Some of these numbers (the Alliance 100XXXXX series especially) get used across multiple seal sizes depending on axle application - don't assume a partial match. Pull the old seal, read what's stamped on it, or run your truck's VIN and axle tag past us before you buy.
Ordering From PartStop
We're in Tacoma - if you're local and need this today, call ahead and we'll have it at the counter. Otherwise it ships out same day for most orders, doesn't matter if you're in Spokane or Sacramento.
At $75.99 this isn't the cheapest seal we carry, but it's not the most expensive way to fix a hub leak either - especially compared to what happens when contaminated lube eats a bearing. Comes with our standard 6+ month warranty.
We can't guarantee fitment sight unseen on any part - too many axle variants out there. Give us your VIN or the number off the old seal and we'll confirm before it leaves the shelf, not after it's on your dock.
47697 Cross-Reference & Interchange Numbers

Frequently asked questions
Does 47697 fit my truck?
Depends on your axle, not just your truck model - the same tractor can run different axle manufacturers depending on spec. Give us the VIN or better yet the number stamped on your old seal and we'll confirm it matches this 4.766" x 6.311" size before you order.
Is this the same as the Alliance 10045887?
It cross-references to it as far as physical dimensions go, but Alliance repackages parts from various sources, so lip style or minor construction details could differ. If you had the Alliance number in the truck before and it worked fine, this should interchange - but check the numbers side by side or ask us first.
How do I know if I need the seal or the whole hub is shot?
If the leak stops after seal replacement and stays stopped, you were fine. If you're getting play in the hub, noise, or the seal keeps failing in the same spot, the bore or bearing surface may be worn and eating seals - that's a different repair. Worth having someone look at the hub before you just keep swapping seals.
