Is the Toyota rear main seal worth all the extra money over the aftermarket rear main seals sold? I'm looking at Cool Cruisers and their aftermarket rear main seal is $18.93 vs the factory Toyota seal at $63.98. I try to stick with high quality parts as much as possible but at over three times the cost I'm wondering if the aftermarket seal will do.

I don't think you want to install the rear main seal twice....

OEM all the way, while it's a 5 minute job to pull out and put in, it's a days job getting to it, your OEM one has lasted at least 25 years, so a few extra dollars will save a lifetime

For me, OEM. It will definitely work, while the aftermarket (not knowing the brand/manufacture) should, might, ought to work I think.

A $45 savings is not worth doing all that work a second time.

factor in the aggravation/pain level if you were to need to replace the aftermarket seal after just a short perod...then figure out how long the stock seal has lasted. Then figure out how much your time is worth.

Just some definitions cuz they're usually misused:

OE = Original Equipment. Just like the one that came on the vehicle when new, or a factory upgrade. Dealer branded, i.e. Toyota.

OEM = Original Equipment Manufacturer. The company that was subcontracted to make the original component for the Vehicle manufacturer also makes production runs of the same component for the aftermarket to sell under it's own brand or sells to others to re-brand. Usually identical to the OE component, but not always, and not always the same ISO level. However, I've yet to find a Toyota OEM that is not the same quality as the OE component.

I'd most likely go with the OE (lol Spike). I'd ask for a better discount though or contact the Beno etc on here. I found with dealers you need to tell them you have heard Land Cruiser club members get better rates on parts, like jobber rates, as we are Toyota enthusiasts. If that dealer doesn't provide you a discount go to another. I've always heard of them giving a better discount for Land Cruiser owners. We are their legacy keepers.

That said the aftermarket is probably a japanese brand and of decent quality. But I would not put in a chinese copy part, which is why I would go OE.

I am going OE when I do mine again.

Can I trust this product to be OEM? - Tacoma World

Just received this seal from an Amazon order.
Its supposed to be a "Genuine Toyota - Type-T Transfer Case Oil Seal"

Can I trust this seal to be OEM as advertised? I've attached a picture of the way it arrived. There was no packing slip from a Toyota dealer like most of my previous amazon orders that claimed to be Toyota OEM. There was merely a clear ziplock stye bag with the seal in it. Ive taken the best picture I could of the seal.

It is marked with: NOK 10.1 BGE


Question: who did you order from (i.e. who was the seller - a dealer?)

As far as packaging, I've gotten seals like that from dealers, so it seems like it could be OK.

Top vs. bottom?

Could be wrong seal as well. But still might be OEM, which is OP's question (so really, there should be two questions )
NOK makes plenty of seals that are used for brand new auto manufacturers.
I'm not saying that specific NOK seal is the right one for where you want to use it, but I am saying I'd verify that's the correct NOK seal through cross referencing, and if correct I'd use it. NOK is quality
I'll be the first to admit I still order stuff from Amazon and Ebay. I got my OEM water pump/timing belt kit from Ebay, but that was only after extensive research and many many recommendations from people here, so for me that's definitely the exception to the rule. Even then, I was still taking a risk. It turned out fine, and I'm sure there are plenty of people who've gotten the good stuff from Amazon, too. For critical parts, safety equipment, you're way better off getting it direct from a vehicle specialist, or as in the case of safety equipment, from a off-road supplier, rather than Amazon.

I just don't have a lot of confidence that Amazon really knows what they're selling. I've seen numerous times I'm looking at a part they say fits my truck, and I know for a fact it doesn't, and visa-versa.
