Heavy Duty Rear Axle Seals

[psea17]

Wondering if anyone knows of an alternative to OEM rear axle seals that might be beefier.

Thanks,
psea

Yup!! But looks like those are for non-abs rear axles. any idea if they have ones suitable for abs axles? took a quick look didn't really see anything. will give them a call tomorrow. THANK YOU!

What's wrong with the OEM ones?

 

[psea17]

they keep failing resulting in leaking gear oil

 

[brillo_76]

If your oem ones keep leaking something else is wrong like plugged breather and or really warn axle bearings.

axle bearings replaced w oem amd the breather diff resides at the gas cap. both like new.

Did you verify the new seal is riding on the retainer at the right spot? Oem seals should not fail that regularly there has to be something else wrong and I doubt heavy duty seals will fix your issue

ohhh yeah. followed timmy's video to a 't'. even used new retainer rings.

Could also be a bent axle housing or axle shaft, scarred axle housing, scarred axle retainer, or misaligned seal. I had to do my rear axle seal a couple times on one side before i figured out the housing was scratched. I installed the axle seal with a coating of gear oil rtv on the outside circumference of the seal and put rtv where the retainer and axle shaft meet.

Did you use sealer under the retainer rings?

 

[psea17]

sure did! i need to take a closer look. the stealership told me it was leaking but im not seeing anything on the tires.

If you can wiggle the abs sensor out and look on thr abs gear for gear grease. If it's wet in there. Your seal is definitely leaking

They make a pile of accessories and parts for our rigs and Toyota in general.

Marlin makes seals for the front axle on the FZJ80 and they are known to be trash. Maybe their other seals are different, but this is what I have heard so far.

Definitely pull that sensor out. Are you getting an ABS light time to time? Happens when the sensor is covered in oil. Did you do the rear axle seals yourself?

I used these on the last rebuild, going strong so far:

Trail-Safe Seal, Rear Axle Toyota (Pair)

I also had nics in my axle shaft from when the PO cut off the retaining rings so I added sealant to the axle as well as to the inside of the seal to axle housing mating surface to make sure nothing leaks past.

When you say you made sure it is riding on the retainer did you measure them? Also, you made sure that everything was pressed together when you measured? I've seen guys have the bearing not fully seated and have a little slop, which skewed their measurement and caused the retainer to be pressed too far down once the axle was installed and torqued (hell, I've done it once or twice myself when I was in a rush).

One other thing I've seen is gouges on the axle from cutting off the old races. I know some guys like to put sealant as they press the parts on the axle, but in this case it still slipped under the retainer and bearing, customer had the previous shop buy him a new axle and bearing job (was only a month old.)
