Transmission Fluid leak driver side axle seal area
 
My daughter has a 95 maxima five speed. We discovered a small leak around the seal according to mechanic. The seal has been replaced twice now with factory OEM (?? good seal). Still leaking. Also, seems to leak only after higher speed driving, and not so apparent when driving around town. Couple questions. What is the problem? Was told could be a worn axle. Hate to keep doing trial and error.

Second question. What kind and size tool do you need to check the trans oil level? Where should level be. Would it be ok to check level periodically and keep up until she can get fixed.

Thanks. Mike.

Your problem could be a worn axle or a worn differential. If you grab the innver cv joint on the left side and push up and down it should only move a very small amount.

Here may be your problem:

the problem most liklely is that the differential is worn out. See the above linked article about a 'Mysterious Axle Seal Leak in a 1993 Maxima'

"The passenger side axle on this model transmission is a two-piece axle. The inner section of the stub shaft is supported by a pillow-block bearing that is mounted to the side of the engine. Unlike a one-piece axle, the stub shaft does not have a constant velocity (CV) joint at the transmission end. The side gear that the axle is splined into is the only thing that centers the axle. The clearance between the side gear and the carrier must have been more than the seal could tolerate."

second question
 
Thanks. That was very helpful. It sounds like that applies to the passenger side, but this is on the driver side. Would that be the same proble.

What about the second question...."Second question. What kind and size tool do you need to check the trans oil level? Where should level be. Would it be ok to check level periodically and keep up until she can get fixed."

I'm about 90% sure it's a 10mm hex wrench.

below is a link to a maxima maintenance blogger
My 2003 Nissan Maxima SE

he got his 10mm hex tool at lowes

In general, a hardened polished steel shaft is not going to wear out with relation to an oil seal....the issue always must be that something is moving laterally. The chance of multiple replacement parts being faulty is very low, and the system is not under pressure, so most likely something is moving laterally.

The end of the splined axle shaft is retained in the gear by a a snap ring, and I suppose there is a the possibility that the shaft is not seated all the way or snapped in, but in most cases a shaft that is not snapped-in will pop out within a mile or two of the shop.
