someone replaced my 90w with creamer... (1 Viewer)

[Aalien]

I parked my 40 for the winter, and pulled it out yesterday. I've had a t-case leak for a while (at the rear AA mount), but I noticed that I was losing a really milky 90w/water mix. I drained the t-case, pulled and drilled the AA mount, and refilled. I decided to check the Trans, same thing, thin milky mess. First question is how did I get so much moisture in there? I've owned this for 4-5 years, and due to some issues it has not been really off roaded yet, it has never been in anything deeper then a parking lot puddle (the hard-top has been on all winter).

Secondly, the rear of the T-case housing where the AA bracket is mounted... yeah, all the bolt holes are partially striped. As I see my options, they are remove the case and cut new threads a size larger, OR I have an SM465-NP205 combination sitting in an old K5. I am afraid the rear drive line would be so short it wouldn't work, I have heard of the offset rear diff with a 205 in 55s, but have heard nothing about it being done in 40s.

Thanks

did you check the fluid four or five years ago when you got it? could it be left from then? is it parked where it is exposed to weather, could it be condensation?

Boy, one could talk for hours on all the possible solutions to the many issues in those two short paragraphs.

I dunno about the oil. It's either water, overfilled and aerated or combo. Pull a sample and have it analyzed if you really want to know what is in it. It was either there before or got in somehow since. I highly doubt there could be enough condensation to turn some 3 quarts milky.

Regarding the LC offset axles, search here or go back a few issues in Toyota Trails magazine for an excellent write-up on grafting a LC housing with the outter axle housing, brakes and rear axle shafts from a minitruck to get your very own LC centered rear diff.

here, I'll make it easy for you....

Thats my guess; the previous owner used it for water sports.

Any marks on the tailgate where the Evinrude was mounted?
