J33ps Posted March 27 Share Posted March 27 Hello again! I'm going to be crawling under the truck tonight to disassemble and inspect. Fill plugs on that t-case are leaking but it's also leaking through the yokes. Not sure if it's both or just one. I recall the PO said he messed with the driveshaft but he couldn't tell me what exactly he did. It had a 3" lift which I've removed. It was some crappy RC springs and such. I think the leafs are stock. Anyway he was so vague and couldn't really remember what he did so now I'm thinking I need to confirm my shafts are correct, especially since I brought it back to stock. Do you guys know what a comanche stock setup is in regards to driveshafts? I plan to pull tonight and I can grab some measurements of mine. I'll snap some pics too maybe someone can spot something. Thanks! Link to comment Share on other sites More sharing options...
Eagle_SX4 Posted March 27 Share Posted March 27 This thread is probably the best compilation of all the shaft lengths in stock form. Link to comment Share on other sites More sharing options...

J33ps Posted March 27 Author Share Posted March 27 Looks like it’s just leaking on the front yoke of the NP242. Curious about this yoke coming off the D35. It seems to be coning from the pinion but area and not the pinion seal in the axle. Is that a thing? (Pic) Link to comment Share on other sites More sharing options...
J33ps Posted March 27 Author Share Posted March 27 Also how do I know if my transmission mount is too loose? I noticed when I grab the rear driveshaft that I can visibly move the transferase up and down. Seems like the mount is spongy, I thought maybe is some rubber pad and it's supposed to have some give but that doesn't sound right given the purpose of the driveline lol.

Judging by your reaction I may be best just sourcing some stock shafts XD Link to comment Share on other sites More sharing options...

(Pic) Yes there supposed to be a seal under the pinion nut to stop oil from getting past the splines. I had this issue on my transfer case and just used some rtv instead of the seal and I haven't had any leaks. Link to comment Share on other sites More sharing options...

The way to get away with breaking the rules is knowing which ones you can get away with while always having a plan B on reserve. That driveshaft is one to keep a plan B on standby. If the balance is off enough, I could see it being hard on bearings and seals. Link to comment Share on other sites More sharing options...
Pete M Posted March 28 Share Posted March 28 yup, an unbalanced shaft can ruin the pinion seal and bearings. Link to comment Share on other sites More sharing options...
pizzaman09 Posted March 28 Share Posted March 28 If you have a local driveshaft shop, take it there and have it balanced Way cheaper usually than buying a driveshaft. Link to comment Share on other sites More sharing options...
J33ps Posted March 28 Author Share Posted March 28 Good point, I didn't think of that. The length seems fine, I'll see if they can balance it for me then. I'm looking at repair details. I've replaced the pinion seal on my D44 on the wrangler and it was interesting but not super difficult. The dana 35 seems about the same but I'm not getting why it's leaking at the pinion nut itself. That doesn't seem to have any washer or seal to keep fluid in. None of the videos show putting RTV on the splines like you might on the TC side. I guess replacing the pinion seal would fix my problem of it leaking at the center/nut area? Link to comment Share on other sites More sharing options...
