m1009 spots

[Dawookie]

I have noticed over the past few weeks that i am getting spots on the back of my truck after i drive it around. Has any one had this happen or know what causes it?

Oil.

Rear main, axle pinion or trans or t case.

I get the same thing...but only on longer drives. I am not 100% sure what it is but I do know I have a small T-case leak.

Mine was trans fluid seeping around the trans oil pan drain plug. Now that it is fixed, I can't call it Spot anymore...

It's automatic rustproofing.

Apply SPF15 to it...

I had that happen to me before from what I could tell it was coming out the transmission vent. I searched around online for a fix and found out it maybe because the front pump seal was going bad or it could be because of overheating when I drove on the highway as I used to get my 1009 up to about 65 to 75 mph at times. what I did was got some trans fix additive and stopped going so fast so far its been 2 years and no issues fluid is good and at right fill level shifts fine as well, so not sure if the seal was bad or not or just the high mphs causing excessive heat but its stopped.

Mine did the same thing, but only when I drive it from CT to MD, on those types of long drives. It srill does it from time to time, but during the fliud and filter change everything looked normal and clean, so I also think it may have been coming from the vent, as the pan and seal areas are dry/ It's just another thing when dealing with life with the 09.

Just noticed it on my 09 after driving 600+ miles at 70+/-

Just replaced the rear axle because the pinion seal (2new ones) wouldn't hold. Too much play in the pinion shaft. Also had an injector return line fall off and that really made a mess!

See my post here, I had a broken bolt on my rear axle cover.

Same thing happened to me, resulting in the spots. Fixed it, and no spots.

Looks like my t-case is leaking. Going to keep filling it until i get a free weekend to replace the seal. Thanks for the help guys.

Glad you found out where it was coming from and are able to repair it.
