Gear Swap....Help Needed

Well, after mentioning that I need to swap out the gears in my front diff, Wildturkee graciously offered to give me a hand, as I would have no idea what I'm doing. It seems that we will have all of the tools we need except for one thing.

I was wondering if anybody happened to have a press/puller for the pinion and carrier bearing. Also, my cousin is a diesel mechanic, and may have the right parts, if only I could tell him what kind. What EXACTLY do I need?

Also, if anybody else would like to help out, that would be great too. With enough people, (and another set of jackstands) I may be able to get the new rear axle in at the same time. Sorry, I can't buy beers for anybody, but I can provide a pretty good meal at least.

I'm not quite sure when I can do this... It needs to be a weekend....but I'm in no hurry. Ideally, we could catch a time when the weekly trail runs have tapered off, but it isn't ridiculously cold yet. I'm free just about any weekend after this one. Tell me when you're free, if you're interested, and I can work around that (specifically you, Wildturkee).

Um not to sell you and Wildturkee short but have either of you ever done gears. I have swaped gears 6 times in the rigs I have owned and still will not do it myself. I am serious. You screw up the backlash and you screw up the gears. If you or wildturkee (sam) have done this before with sucsess (and lower gears are easier to do than my higher gears at 5.71) fine but be forewarned ok?

Well, I think Sam knows what he's doing... You've done it successfully a time or two, right Sam? Or at least your buddy has...

Id personally just pay a shop to do it.

Then you also have the re-assurance that if its NOT done right, it falls on them, and they should fix it for free and make it right.

Yea, those taco front diffs are even more fun. They require a special dial indicator to measure backlash, normal dial indicators don't work. Spliting the cases every time to inspect tooth contact is a pain. I don't like the "clamshell" design.

I'll let you see my pattern to see that it is tits. Anyone can blow a diff quick, just look at me. I can ensure my setup will be correct.

But..... when I PMed you I though we were talking rear diff. I could charger 100 for that because I have all the tools to build that diff. I don't have the "special" dial indicator. I could check the price on one of those but I think it would be cheaper to go to Mike at ORS (he has one). But if you want to cover the cost for the tool I'll still build it.

well i thought the front diff was a removable 3rd member, not a clam shell type. if it was a removable 3rd id be able to do it correctly and have a few times, but the clam shell type count me out, sorry man.
I have access to the special dial indicator for the back lash. just so every one with a removeable 3rd member knows

Do not DISTURB! Im disturbed enough allready!

I have a normal dial indicator, just not the one that measures radially.

Ok, well thanks anyway. I really appreciate you offering to help.

I may go to ORS....I have been meaning to check them out anyway. It may be a little longer until I will have the cash, in that case. What do you think a shop may charge? I'm just guessing $150-$200...but I don't know.

thats probably low due to the amount of labor invalved to remove the front axel assembly, how ever if you pull it your self and take it to them then it might be closer to what you are thinking.

Most Dial indicators the measuring device moves in/out. The one need for the taco front moves side to side. I just have the in/out one.

Okay guys, I really need help now. My truck is disassembled in Troy and Molly's driveway, where it will need to stay for a couple days. We have the diff pulled, and I am taking it home with me. I need my diff set up ASAP, so that I can bring it back to Longmont, and get it in the truck. Please let me know if you can help me out, and when. My diff takes a dial indicator that moves side to side, rather than in and out. I'm getting kinda desperate here....

I know this is hindsite. But I think while the diff was still together and out you should have just taken it to a tech. Diffs aren't something just anyone can fuck with. I also wish I would have watched this thread a little closer so I could have made it a little more clear that this is a job for the pros. Good on ya for trying though.

Is IFS something you can get penicillin for???

ask molly for anthony's number.... kinda suprised she didn't give it to you already. he can get you setup. he has done quite a few gear setups for toys and stuff.


dunno what kind of funding you have to throw around but harbor freight sells a 20 ton press.... that is what you need to press everything out for the pinon gear. as for setting everything else up it isn't something that you cant do yourself. read up on it about how the gears should mesh and backlash and preload. find a place that will sell you marking grease and take your time. I have seen setups last for a long time that people set up at their houses...

She was going to, but we both forgot. I should call her, soon, or maybes she will see this.

BTW, Molly and Troy, you are the greatest! Thank you so much for everything you have done for me, and everything you do for the club!

Well, rest assured, no press nessesary, just prefered.

As for special Dial Indicator, at this point, why not buy one yourself? I doubt they are much more than 50 bucks.

Here's the plan. Today, I'm going to make a bunch of phone calls and get my parts, and line up the labor. I think I will just take the diff to a mechanic that has done a couple things for me. I'll have him do it on Tuesday, and hopefully be able to take it back up to Longmont by Wednesday or Thursday.

Okay, I've nixed the mechanic idea. After having a conversation with the guy I was going to have do it, I'm not taking another thing to him again. I've looked at other places and got really high price estimates... The best I got was "200-ish", at Drivetrain Industries...which I may consider. After hours of searching, with my left hand typing, my right hand writing, and my ear to the phone, all at the same time, I have not been able to track down an install kit in the Denver area. I did find a crush sleeve, and a replacement bearing, for the one that was destroyed. Troy, I will be giving you a call shortly.

Untill you try to do it yourself. A removed rear diff would be cheaper. Those "clamshell" diffs suck. Usally double or triple the time of a normal diff build.

And you only add like $200 for R&R

Just think if the dealer was going to do it. Pricing starts at $550 and 90% of the goobs couldn't do it, they would cry like they had sandy crotch.

Good to hear. Thanks Molly. I'm dropping off the diff at a place in Denver that was recommended to me, by my buddy that I go and see at Napa pretty frequently... He can have it to me by the end of the day, and he's only charging $150. He's a diff specialist too, so I feel it will be okay.

I'm looking to do the install into the truck Thursday...Let me know if that works, Molly. Wednesday would be akward with the early trick or treaters...
