No worries at all. That is how we learn and help each other.@GVegasG Sorry got a lot of questions from that last post- Was all that gear oil in the tub present when you pulled the axle?
Be sure you use a new Oring with a new OEM inner seal- also curious what tool you used to install the inner seal?
My rear axle came with synthetic gear oil when I bought the vehicle. It had leak on the passenger side. I switched to conventional gear lube and it has been leak free for 2 years.Not exactly sure what was used before.
Interestingly enough one side is dry. So the oil theory is probably out at this time.
I will keep an eye after changing the seal.
Great info. If the seal change does not help, I probably have to do that.My rear axle came with synthetic gear oil when I bought the vehicle. It had leak on the passenger side. I switched to conventional gear lube and it has been leak free for 2 years.
It is smooth and even. It also looks like seal is sitting in the middle which is where it should be based on my research.View attachment 3116291
Drag your fingernail over that wear groove on the spacer- if you feel any ridge- that points to part of the problem of gear oil working past the seal
Benefit if you do the other side now before the gear oil leaks is you can likely just change the seals and not have to do the full bearing assembly. From my memory the seals are pretty cheap so that might be a good path forward so you dont have to press everything.It is smooth and even.

I think perhaps my mechanic had not used synthetic before. However let’s be honest 23 years old car - probably time to change it. Will see after the change. Will probably have to tackle the other side later. There are no leaks but brake sensor was bit wet. So I think it is just matter of time before it gets outside.

I agree @2001LCHe noted that: rear axle seal leak, is sign bearing(s) need replacing. But it's the chicken or the egg story. Gear lube getting into bearing grease, will damage bearing as grease than fails. Bearing play/vibration, will damage seal.
@GVegasG it would seem you prove his point, at least in your case. This assumes installed seals correctly, breather working as it should, gear lube not overfilled and no excessive vibration.
Don’t fret - With a little ingenuity and elbow grease, you can replace the bearings without a press or SST. Just Google “Toyota pickup 4runner Tacoma replace rear axle seals bearings without press”. There are plenty of videos showing how to do it without a press. Although the axles are different on those vehicles compared to a 100, they all are semi-float with the bearings pressed into the hub/onto the shaft the same way.I really don’t want to buy press and the tools from eBay. Perhaps can find a shop nearby in SoCal that can press out and press in.
Did the new bearing fix your axle leak? Running into this myself.Update: it is still leaking, more on DS. I think I have no choice but to change the bearings.
