Well you should be able to start with the pinion depth you have now, and just set the new Carrier up with the same ring, but at times when you cant get the right pattern then you go from there, I would say the factory pinion depth is the closest your going to get with out setting up the carrier, when I set up used gears and I have the old shims, I use them as a starting point, so you are already half way there, and like you said carrier bearing backlash and so on, the main thing is to make sure you have the right series carrier, you can see the difference when you put them side by side with out the carrier bearings installed.
If you know or have checked then you are good to go…

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Also should I buy a master rebuild kit or just source out the parts I need?

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I would say if the bearings (carrier) are good, I would swap the shims on the carrier as well, and do a test installing the carrier to see where you are, check the pattern and go from there, If you are replacing a factory open carrier to another factory open carrier you will be surprised how close they will be, and if then you need to move the carrier back or closer buy a Mini shim kit it will have (should) a seal, pinion & carrier shims with making compound. When the axle housing is out I use the spreader on the Dana models, but looks as though you already have the gears out so you have a good bead on how to do it.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

The new carrier did not come with bearings attached, but my original ones look good, should I get a new set anyway and use the original as set up bearings? I think I read that this was suggested because taking the carrier in and out and pulling bearings and adjusting shims multiple times can damage a set of bearings real quick.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

It’s always best to install as many things as you can New while your in there so yes that’s a great way to do it, I have a set of bearing slugs that are the same size as the bearing with races and also a nice bearing remover, and it makes what your doing very easy, once you have this kind of stuff it’s hard to remember how I ever did it without them, so yes your on the right track… They also sell set up bearings, and they save a bunch of time and money as well, the last set I bought was many years ago and back then they were around 40.00 for the set, no races, good investment even if you only use them once.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Ok good to know, Ill look for a pair of set up bearings.

So if you were me, you would go ahead and put the carrier and everything back in before messing with the pinion depth?

Maybe ill get lucky and not have to jack with the pinion depth and all the little things that go along with that.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

About the only thing you can do at this point different, is reset the pinion depth to the center point, and start over, when I do the exact same thing I go with the factory set up until it proves to be wrong, and considering all the pinion bearings and races are in good shape and so on. If you have a or have access to one you can check the pinion depth with a pinion depth gage, the pinion should have a + or – number on the head of it that will give the number that the factory recommends to start at when setting up the pinion, but IMO it’s just extra steps (if) the ring and pinion had no issues before you pulled them out… Yes I would do a test and go from there...

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Ok good deal, thanks for letting me pick your brain. What part of Texas are you located in? If I cant get this thing figured out I might have to pay you a visit lol

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Anytime, with your carrier swap, you are very close IMO, and you have the confidence that’s needed to do what you are doing. I’m north of you about 150 miles, in the Tyler area. What Lockouts are you going to run?
Please feel free to stop by and visit anytime! When you get the 4L80E in there, you should have decent fuel mileage…

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I got the Dana all put back together. It wasnt as bad as I thought it was going to be. It took some time and patience but I finally got the backlash into spec and ran a pattern. Its probable not perfect but it seems acceptable. I think the pinion could be moved out a hair but im happy with it.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I also got the fenders and hood sanded down and primed. I have some body work to do on the fenders and tailgate. I want to have everything primed up pretty soon so I can start hi-building and blocking. I'm anxious to paint, its warming up nicely and I want see what it will look like with some fresh color.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I haven't got as much done as I wanted in the last couple weekend, i've been distracted by building a chicken coop and messing around in my garden.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I don't know what I'm more impressed with. Your welding, trucks lack of rust or the fact that your wife helped. My wife might doesn't know what grease is. Lol

Wow, that is turning out great! I like it :metal:

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Thanks man, I just read your build thread, yours looks good too. I like those leaf springs, I haven't made a decision on which brand to go with for mine. I'm leaning towards the 8" skyjacker soft rides. Have you heard anything on these?

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Thanks! I did some limited research when buying mine, but ended up with the Tough Country springs because they were more economical (on sale :lol:). I'll have to see if I can dig anything up for you.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

Here are some of the threads I had. For the most part, it looks like a dead heat. Looks like most people believe (and are probably right) that the shocks will make the biggest difference. Mine are the Tough Country Nitros. I'll let you know how they ride in about 10 years, when I get the truck done lol

If you are looking for a good ride, I would check out a 52" spring swap. 2" spring and a zero rate add a leaf would get you ~7" lift I think. Shackle angle is important. Www.diy4x.com

I had Friday off so I got some more stuff sanded and primed. I used chassis saver on the core support and wheel tubs and inner fenders.

I sand blasted my tailgate, it had some heavy pitting so I put some POR-15 on it before I primed it. Got the doors sanded down with some 60 grit and primed them too. All that need primer now is cab.

Worked on the cab all weekend. I gutted the rest of it, sanded on it and sandblasted some rusty spots. I filled in the gas tank cap and primed everything up.

Great build! How big is your shop? From some of the pictures, it looks pretty good size.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

great build.. and I agree, pretty impressive your wife there helping pull the engine,, mine knows what grease is,, only to yell at me when I track it back in the house LOL

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

The whole thing is 72 x 84, our house is built on the inside of it. We actually just sold it this week. We are down sizing everything because im trying to open up a business and cant afford the mortgage and the risk of the business. It was nice having it tho.

Re: 1969 k10 lwb to swb, 1 tons, 6.0/4l80e/np205
 

I need to take some pictures but I spent the last few weeks doing body work, lots of sanding. I re-epoxied the spots that I sanded too much on and got down to bare metal, then I sprayed two coats of Hi-Build primer. So now more sanding lol.

After hours of research I decided to go with the skyjacker 8 inch springs for my build. I have a set of 6 in tuff country springs that rode well also.

Its getting there, its a slow process. I've got just about everything picked out and my shop location. I'm just waiting on the bank and financing. I haven't got to sand anything in a while i'm having withdrawals

Do you have any pictures with of your truck with the 8" lift on it?
