My wife has a 1993 landcruiser automatic with lock differentials. On the drivers side when turning we heard a click. We told the mechanic to change the axel on it. As thr seals are leaking out from the ball joint. He told us the truck has 4 axels. Inner and outer. It didn't sound right to us. He's charging alot. How many axels does this truck have? Thanks

You don’t have ball joints so maybe you mean the wipers on the birfield?

Otherwise yes, technically there are two inner and two outer shafts just like every other solid axle but but only two axle assemblies.

He might be referring to the axle shaft & CV separately.

I know the seals were leaking. I prolly mis named the part. Each wheel has a round ball where I see grease coming out .

The mechanic is correct that each side has two axles....but we typically refer to them as the inner axles. See pic below. The round bit is the birfield joint. the clicking you hear is from the balls that make that joint function getting stuck in the worn parts of the birfield joint. The clicking will stop when the birfield is replaced. the leaking grease is from a failed inner axle seal. the inner seal prevents gear oil from the differential from leaking into the knuckle which is full of grease. When the oil leaks past the seal and into the grease it can flow down into the knuckle and make that grease flow past the grease seals and wipers on the knuckle.

So the clicking is a worn birfield joint which means replacoing the inner axles, and the leaky grease is from a failed inner axle seal. But the crusier has a couple more seals in the front axle that get repalced when thye get taken apart for service.

There is an inner axle shaft on each side. The birfield is sometimes referred to as an "outer axleshaft.

Unless you are a skilled and knowlegeable mechanic yourself, capable of diagnosing and repairing the problem yourself, never take your rig to a mechanic and tell him what to replace. He might do just that. Whether it is the actual problem or not. And you will have little to complain when the actual problem is not fixed. Tell him what the symptoms are and let him determine what need to be done. Put that responsibility on him. It is part of his job. You want the problem fixed. Just replacing some particular part that may or not need it does nothing for you. IF he is not capable of diagnosing the problem... he should not be working on the rig for you.

$1000 is cheap for just the labor for this job. Book time is 2.5 hours to replace one inner axle shaft. If the axle is not grooved from the seal wearing it, then it would not need to be replaced. Still has to be removed for inspection. If it is grooved, just replacing the seal will not solve the leak. Either way the time would be the same. There are offset seals that are available and there are sleeves that can be used to address a grooved axle without replacing it. Neither of these affect the labor time. (Actually, installing a sleeve will add a small amount of time.)


The clicking is from a worn birfield. Replacing or not replacing the birfield will not add any labor time. Not replacing it will of course not stop the clicking (or eventual failure of the birfield).

This job can not be considered complete without replacing all the contaminated grease. It can not be considered first rate without inspecting and possibly (probably) replacing the wiper seals as well as the inner axle seal and the knuckle and wheel bearings. The time to do this is not included in that 2.5 hour figure.


Edit: Also, if one side has problems... both sides need attention. They have the same mileage and the same wear.

We told him about the noise and when he took it apart that's when he mentioned the seals, etc. He said it would take time to do each side. Since he's alone.
What you just shared with me is very good and important stuff. I appreciate it .

Where did these upvote down vote options come from? Is this some new feature? Or have I been stuck in the echo chamber of my build thread?
