Yeah, I lost that about 1 and a half from your house. Im not sure the road name. But, it was somewhere before that little grade. I heard it hit my inner fender but wasnt sure ehat it was. Until, I went to clean my battery terminals, next morning and had no wrench or socket. I had used it 5o try to tighten up the hold down on battery.

You can get the build sheet that has all pertinent info. Engine, gearing etc. A mechanic downloaded it for me.

[@chud327]

Make sure it is all stock, mine was 30 something years old. It has different engine, trans, rear end, etc. Thanks for watching

[@19jody72]

Easy to mark a spot on the shaft..turn the wheel one time..count how many times the spot on the shaft turns..

[@chud327]

That is one way, I feel my way is more precise unless you have a degree wheel on you drive shaft. thanks for watching.

[@johntate4638]

It is way easier to find the build sticker in the truck. It is inside the glove box most of the time and will have gear ratio printed there.

[@curtisdefreece9921]

Just turn the wheel one time and count the driveshaft rotations. Even easier

[@chud327]

I was turning just one wheel and counting driveshaft rotations. Thanks for watching.

[@mikebice3211]

Count the teeth on ring gear divide it with pinon you’ll get 383. 411. 513 and so on

[@chud327]

That is the most precise method, but hard to do if you don't want to pull the rear cover and dump your oil... Thanks for watching.

[@chuckcrandell6929]

What this video and many others on this topic fail to clarify why there is a multiplication by 2? On some You Tube vids there is no multiplication. Another thing that vids do not clarify well is what type of carrier an axle under analysis is. Open/standard diff, locker diff, etc type.

[@chud327]

Sorry about that, this one was a locked rear to start with. That is why one tire had to be blocked. Since only one tire spins, the tires spins twice as much, therefore you need to divide by two. If you have a spool, you could jack up both sides and not divide. I hope this helps and thanks for watching.

[@dodgecharger1704]

93 GMC Sonoma stock rear in the motor is a Chevrolet 350 transmission is a three speed turbo. What is a good suggested rear end to do a little hot rod in but at same time I’d like to be able to do 80 miles an hour or faster at the highway

[@chud327]

I would go with a 3.42:1 if performance is more important than gas mileage. It is an all around good choice. I had a 2.73:1 in first car and it did good, especially for gas mileage and the way gas prices are going... Thanks for watching and good luck. Are you doing any video on it?

Thank you Chud. Very helpful. I have a 79 G20 Van running big block and am currently fitting up a 4l80E auto. I am modifying converting the tail housing to speedo cable drive. I need to find out the diff gear ratio in order to calibrate for speedo accuracy. Cheers.Very much appreciated.

[@alexlovato5210]

Okay I get this but I broke my rear and one wheel completely off and I think I shredded the internals in the pumpkin should I just crack it open and look for it on the gears

[@chud327]

That was s what I decided too. If you check my current build, it has the same wheels too... thanks for watching!!

It's a little more sketchy on an automatic, but works all the same. Fantastic way of figuring out your gears

It was a beautiful day in my neighborhood, thanks for watching

[@notoriouselwood9253]

By the way, many of the s trucks came with a factory spiro-locke differential. Only locker available stock. And does NOT spin both tires in reverse. Only when power applied going forward. Gets you stuck most every time.

[@chud327]

Thanks for watching

[@timmyohearn1639]

How is the best way to make sure that I ordered the right driveshaft? there are so many different ones. Or howd Do you measure for wheelbase

[@chud327]

I measure from the universal flange to universal joint flange, then I usually go to the junk yard and try to find one that is the right length. Only thing is they move the vehicles at the junk yard with a front end loader and most driveshafts are damaged, but if you look long enough, i can find one not damaged and the right length. We also have a drive shaft shop that will build anything you need. You can take one from the junkyard and they will shorten it for you. The junkyard only charges about $18 if you can find one that works. If you tell the drive shaft shop what vehicle and what transmission you have, the guy might already know which one will work. Hope this helps and if you watch my latest S-10 build for about last October, I walk you through how I find my driveshaft. Good luck and thanks for watching.

[@choloshamangaming2283]

what if yo uhave bigger tires will that affect this process

[@chud327]

You can still check you gear ratio the same way. thanks for watching.

I put a set Irock-z rims on my 1985 GMC a 4zx4 S15 and I noticed they were marked front and rear on the actual Rims well some reason on the front the rim stick out like at least a couple of inches past the Fender wells where as the back there tucked inside the Fender well is there any reason the offset might be different from the back to the front if I were to switch it would it make any difference or do u know thanks

[@hg2.]

Can't get a grip on why there's the "multiply by 2". ???

[@chud327]

You only have one tires spinning so that will spin the drive shaft twice as fast as if both tires were spinning. So if you do the math and it says you have a 1.865 you would double that and get a 3.73. If you rear has a spool which keeps both wheels locked together, they would spin exactly the same amount of times. You would not block one wheel and you would skip the multiple by 2 part. I hope this helps and thanks for watching.

[@dalefeekes313]

turn the wheel twice the driveshaft should turn basically 3 and 3/4 turns or 3.73 times

[@chud327]

That is a good and quick way to estimate what you have. Thanks for watching.

[@RalphSampson...]

Why not just look at the tag? That one likely has GT4 stamped on it, which is a 3.73. I get it. Just in case the tag is missing, you can use this method. But, still, he could have said, "If this tag is missing......".

[@fastnasty6627]

To get a general idea setup like he did turn the wheel one turn, watch how many turns of the driveshaft if about 3 and a half you have 3.42, if shy of 3 turns you have 2.73, if 3 and 3 quarter turns you have 3.73, if little over 4 turns 4.11 and so on.

[@chud327]

That would be a good way to estimate it and thanks for watching.

[@chadgenthe3445]

Great video if I did it right I have a 4.10, but the question I got is I checked if I have limited slip rear end and I do but when I turn the tire the other side barely turns is that normal

[@Redeemed427]

+chud327 You know, I never thought about a video. I think that's a good idea, like I said it looks good but a video on each $$$ step lets other people judge what they may want to do first, or wait till 3 or 4 steps into it. I know I'll make a walk around and under the hood, and inside so I can see progress. I'm on a budget though, so it'll take a bit, all nice things do. I forgot to mention on your S-10, I liked the way you used the VW gas tank, Hea if you got the bed off one, start making in nice and custom, clean it all up and paint it. Git er done. I never thought of buying a little locker, I'll have to check into it, but again, if I got it apart I'm going to change Rings and Pinion, it's going to be a toy, something to drive and cruise in, gotta be dependable. Thanks, if I get to bring it home tomorrow I'll post a quick video for all. We are still a couple hundred off on the price, but I don't see it as a deal breaker, thanks Chud327.

[@leecox1513]

I'm confused. You jacked up both rear wheels, then immobilized one of the wheels. Why not just jack up one rear wheel so that you would not have to jam a hammer beneath the wheel on the opposite side? It would have the same effect, right, or did I miss something here?

[@chud327]

Thank you very much! Found your video right on time. Going to change my gasket tomorrow because of a leak.

I thought Oh great, I got too many things to do on my truck that needs attention, everyone else is busy too, but I gotta make time to please Dad and figure out the ratio. Didn't realize how easy it is until your video, lol! And now I'm really glad my dad asked because this would be the perfect time to check the exact ratio. I don't know what it'll tell me but I guess my dad will give me a lesson when I tell him what mine is. Btw, what color did you end up going with?

[@chud327]

It is soooo easy and I am so glad it helped you. Thanks for watching. Let me know what you find out.

[@bandita445]

I'm embarrassed to admit, I had a really hard time with the differential and got myself in a pickle. My plan was to torque the bolts on the cover to 20 ft lbs, starting off lower. As I tried torquing to 10, several of my bolts broke and now I guess I have to drill them out. I picked up some Grade 8 and 5 bolts (because store didn't have enough of the 8's). I don't know what grade my original bolts that broke are because there's no markings on the top (just has a #3 printed on top). The grade 5's I picked up, I don't even think they're heat resistant. Will these suffice as temp use until I can find the right bolts, or do I need to replace the gasket again once I remove the temp bolts? I presume I'll get a small leak once I remove any bolts, so not sure if that would compromise the new gasket I just put in. As far as the gear ratio goes, no ratio markings inside :( Got some numbers but don't look like ratios. I'll send a pic if I can figure out how. I counted about 1/2 way for each of the gears, 24 and 8, so I guess 3.0 would be a rough estimate. In the back gears (the one with about 16 teeth), had a small etching that looked like 2.756. Not sure if that represents the ratio.

[@chud327]

I would love to see the pictures and the bolts shouldn't need to be heat resistant, rear end shouldn't be getting hot. You could use a new gasket or some silicone sealant. The number on the gears should tell the story. If the big gear would be about 24X2 which would be 48 and the little on the back is 16, then 48/16 = about 3.0. I wish you knew the exact number of teeth on each...

[@bandita445]

Good to know that heat resistant bolts not needed, thanks. So I guess as long as there won't be any leaks, I won't need to replace them. That will save a lot of time. I wish I was able to count all the gears too. Wasn't able to get them to rotate and the small one in the back is waaay back (hard to reach). I don't know why my truck always seems to be more complicated then the videos I watch on how to do things, lol! Not sure if there's a way to upload pics here in comments:(. Btw, Happy Easter!

if thats a lockright locker im just letting you know they suck

[@chud327]

I know Richmond made it so it probably is a Lockright. I don't have much power, so maybe it will be ok. I will for sure let you know if it breaks. Thanks for the warning.

[@markramirez9185]

I have 35's on my 05 F150. Trying to figure out if previous owner swapped out the rear end or if its still stock. My shift point are not correct, on the road it kind of chuggs till I let off the accel and then it seems to pop into the right gear. I have a flashpaq tuner on the way to see if I can tune it to perfection. Thanks for your time.

[@chud327]

Mark Ramirez this is a sure way to find you ratio as long as you have one tire turning, count correctly, and then divide correctly. thanks for commenting back and good luck.

[@chevellis4331]

thanks ,thats easy enough !!

[@chud327]

You are so welcome, I hope it helps and thanks for watching.

[@markramirez9185]

Does this method work even if you have aftermarket rims and tires(Larger ones). Please help.

[@chud327]

Mark Ramirez yes, the tires size is irrelevant. It will work just the same with smaller or bigger tires. Hope this helps, what size tires do you have? Thanks for watching.

[@almightyjr9086]

Hey there what car would make a good dones for posi trac for a 93 s10 I’m trying to build one .

[@chud327]

I had an s-10 one time that some one had put a lock in from a Camaro or Firebird... thanks for watching and good luck.

[@guidosarducci3047]

Thanks but question please. Have locking posi. do I still divide by 2? I think it's 3:55 but unsure. have power glide 2 speed which makes it harder to guestimate. I would much rather know for sure. thanks I subscribed

[@chud327]

Good question. If both tires are locked together and turning the same, you would not divide by two. Thanks for watching and especially for subbing. Good luck.

[@guidosarducci3047]

@@chud327thanks

[@chud327]

Anytime!

[@henrydeloatch4450]

what rear end will bolt up in a s10 that is a posi traction and can stand up to a small block

[@chud327]

Henry Deloatch I would think that you could put a locker in the stock rear like mine had and it should be fine. Unless you are going to put some be sticky slicks back there, the back end is so light that it should spin before something breaks. Mine never gave me any problems, but I didn't have slicks either.

[@thomaslockley945]

that same method work if you had a stock tire 275 but u got 35s or any thing like that?

[@chud327]

yes this will work, tires size does not matter. Good luck and thanks for watching.

1:22 old school traction bar.

[@chud327]

Yes, I love those, but when I lowered it, they would fit on any more. I will save them for a future project I guess. Thanks for watching and for the double comments.

[@williamwimberly5362]

cool just hit me up any time what i have is 88 s10 tahoe with only 2200 miles on its like new really lol has a 4.3 in it with automatic trans and would like to get it set up for a v8 or maybe buy one thats already done and strip it or may even just trade this one but from all i have read dont think it will be too hard being it has a 4.3 already but i have been following u and your close to me so figured u may could be some help in pointing me in right direction... thanks will

[@chud327]

+William Wimberly Yea that sounds cool. As for yours, the v8 would bolt right to your transmission. Everything behind the trans can stay just like it is, unless you start making too much power. Motor mount will be on of the biggest things that you will need. Or like you said, some one might be wait to trade you. My first V8 s10 came with the v8 already in it. My neighbor did all the hard work and got tired of messing with it. He bought my full size truck and pretty much gave me his S-10. I then drove the wheels almost off of it. That is when my addiction began. I have had about 14 S10's over the years, or at least that is how many I can remember. I should do a video one day and show all the pictures of my S-10 pickups and Blazers. Some people would get into that... Good luck and keep me updated.
