so i have been meaning to update this, just been short on time. i ran into some issues last weekend trying to run the snakes.(a trail here in utah) My new front differential that i got from marlin crawler last month with the detroit tru trac failed!!! i got lost on the dirt roads trying to find the trail head, in hopes i would run into someone to run it with. (i was alone) when POP! CLANK CHATER CHATER DAMNIT! got out and my front driveline was lying in the dirt with the pinion flange attached to it, it was still conected at the transfer case. I was at just enuff of an up hill angle to loose almost all of my new lukus synthetic 90w. i just changed the break in fluid out 2 weeks ago. ERRR. well it seemed my day was already over, so i tyed the driveline to the frame and started to the road in 2high. just as i got to the road two toyotas came off the pavement, I asked them if they knew where the trail was and they said they were going to run it, and invited me along. so i tagged along. im broke but at least im not alone. so i followed them all the wat through rattleswmake in 2 high! got to waynes world and there was a bunch of guys trying to get through. I watched them for a while and was just about to head home when they invited me to run constictor with them. (mostley cuz i had beer left over from camping the night before) So they helped me take my drive line off so i at least had 2 low. went up the bypass of waynes world and followed them through constrictor. i made it most of the way up, but got beatten by the obsticle that goes between two trees maybe 20yrds before the big obsticle that turn you hard left, from there its a straight shot 50yds to eagles nest. bummed i couldnt get to the top due to breakage but stil surprised i got that far. had a good time though, but very frustrating being broke due to some thing i didnt do! if i broke cuz i was being stupid..... i can handle that, but this sucked! called marlin crawler and they want me to tear it out and ship it back to them. they said they will pay for the shipping fix it and send it back but i still have to do all of that work again! i just hope thay come through for me. trying to be positive but i pulled the drain plug last night and there is some pritty big chunks of metal that came out of it. the passenger side cv wont turn either. so i cant get all of the bolts off! this is going to cause serious problems getting it out! errr! i had to pull the rear back out as well when i first got it because the damn air locker was leaking. awrr sorry now im just venting. lol i really dont want rebuilt crap put back in my truck. i paid for new and perfict and thats what i want! Looks like the pinion flange nut backed off, not sure if it wasnt torqued or the crush sleve/ lock nut was right. it had probably been backing out and unballenced since i first put it on. i never noticed anything before. other than a slight whine when i was in 4wd, but i thought that was my transfercase. with the front drive line off it did get a bit quieter. idk. anyone have any ideas on what might have broke inside due to this? was this for sure they're fault? or was this somehow my fault? (i cant think of how being all i did was put it in and attach the driveline.) what should i expect from marlin crawler on this?/ what would you do?
