What to look for in a used 14 bolt?

Never buy an axle without looking inside first. And you really shouldn't drive very far without them sending pics of the insides first. I drove 1.5 hours out to look at one that instead of gear oil had rusty water inside with crusty ring and and pinion. Another similar drive and the ring gear had like 1/3 of the teeth chipped or broken. Both axles were "working when pulled" and both sellers were "sure everything was good".

Luckily he is taking it to town for me. I just sent him another email asking if he could pull the cover and send me some pictures of it, no point in wasting each others time if its trashed on the inside.

410 would be better for you with33s. I have 35s and 410 and it is perfect. If you want to go to 35 s later you'd already be ahead on gearing. That full floater is a 75 I think it said so I'd want to take a real good look at the bearing and all before buying or running it. I have about 600 into mine right now with buying the disk convertion and new seals.

Here are the pics he just sent me.

Anyone see any issues with it? I am going to tell him to bring it to town with him next time he gets a chance.

Looks pretty good to me. I'd buy it after lookin at the ring gear. No chipped or broken teeth. Doesn't look to be anything obviously wrong. 150 is what I paid for mine and just put in new seals and and added a disk brake kit.

That looks like a good deal... I'd jump on that...

Go with the 4.10's for sure.

the 6.2 diesels sweet spot for the highway is 1800-2000 rpms.

with 33in tires at 70mph youll be turning 2046 rpms.

with 35in tires at 70mph youll be turning 1929 rpms

and especially if you're going to be towing occasionally the 4.10s are going to make your life that much better.

just all around a better choice.

Looks nice and clean, nice pattern, nothing to fear.
