Why do I get the feeling my head is about to hurt.....
-
You look a lot younger than I expected Tate!
I followed most of them but the 2 cut vs 5 cut. Not sure I understood the heel/toe comments and why are there different types? Pros/cons? What is meant by the 2 cut or 5 cut?
-
One has 2 cuts, and the other one has 5. You. Are. Welcome.
fyi.
I will delete my dot posts when I'm done messing with Neck.....which may be a while.
-
thanks

5 cut gears, traditional gears, have a taper to the ring gear teeth and a wider spiral. this can create some "slapping" effect and generate unwanted gear noise in some applications like SUV's and unibody gen 3 Camaros for example. The outside edge of the ring gear is considered the "heel" and the inside edge the toe. Imagine standing on the ring gear with your toes in the center. A 5 cut tooth is higher at the heal than it is at the toe.
The 2 cut gears have a tighter spiral to them, use a much tighter backlash setting, like .003-.006 vs .006-.010thou on the 5 cut, and have teeth that are the same height from the outside edge of the gear, (heel) to the inside edge of the gear, (toe). they are inherently more quiet, and ideal for burbans, and tahoes, and expeditions etc, but much more difficult to get good patterns on. Most techs that have been doing gears for 30 years will have no clue how to set them up correctly and will chase their tails all day.
I'll be 35 in November, and the camera hides a lot of gray, lol.

Very professional videos Tate. :thumbsup
-
Thanks!
-
Valuable info bro!
-
New video on gear noise added to the top.
-
Maybe number them so they stay in order from oldest to newest .......?

Touche'

We've got a pretty exciting build coming up. doing a spin free conversion locking hub kit on a dodge front. shooting Wednesday, and after cutting/editing process probably upload next Tuesday. should be pretty cool with some live action shots in the shop.

Tater,
I sure wish you folks would do a free spin for the big chebby front axles
I know who would volunteer!
-
If the GM wasn't IFS, we would have a live axle system to work with, but at this time the CV axle situation requires extremely expensive custom shafts to work with anything but factory brg/hub assemblies. At some point someone will figure it out, but until then, the factory disconnect will have to do.

Tate, I remember installing a free wheeling hub kit onto my 1st gen Tundra. Was spendy, but I got a regular hub on there
-
yeah I still have hubs for those guys and the cost has gone way down. now I can get a warn set of hubs for up to 01 t100-tundra for $211.64 retail! Lack of a space to bolt the spindle to is another issue, requiring a whole steering knuckle to be engineered for the GM conversion. in a nutshell, it CAN be done, but no one would buy it.

Makes sense
But right there GM is tossing out at least 1 MPG
-
That fact is not lost on me. They would also drastically reduce wear on steering components and axle shafts as they would be static rather than live. But that wouldn't sell many replacement parts would it?
-
I'll trade the 1MPG for the better ride any day of the week.
For what the majority of people really use their truck for it's a better system than a straight axle, IMO
But, if you got the money, you can get square baseballs.

NEW locking hub installation video. just posted yesterday with a little more production value. We touch on the key points and the essentials for anyone who is interested. https://www.youtube.com/watch?v=VM8OOreOytM
-
nice video, so how much did you guys get from snap on for all the plugs to their tools????
-
As far as I'm aware, it went towards the cost of the toolboxes we gave away, but that's marketing side which it looks like I'm involved with but I'm really not. Just another pretty face,
hahahahaha!!!
-
Not sure about all that pretty face business ???
-
Me either :-\
-
Man, your mechanic is super fast!
How 'bout shootin' me a price on that Dodge kit. My buddy has an '06 Dodge and he's been talking about doing this. thanks.
-
He ate his Wheaties Ken, and drinks lots of quoffee. Shot you a PM on pricing.
-
Nice video, but you didn't get dirty!!
I like the hubs 8)
-
Yeah, they are much better looking than the spokesman. They let the real expert do the installation, I just get to cover the details. I haven't been paid to turn a wrench for 10 years now and my back, knees and hands love me for it. slinging tires on semi trucks and doing suspension work beat me up pretty good as a young man. Now I've got similar back issues to Duane and knees that will need to be replaced or at least worked on in the next few years.

Added two more differential tech tips this AM. How to identify and decode Ford differential ID tags, and how to properly clearance a thick ring gear to install the cross pin shaft.
-
Added on a new video w/ GM RPO codes for differential reference. helpful but vague at the same time, the idea is to generate phone calls of course, but here is a reference link that is relevant: https://www.yukongear.com/downloads/productinformation/gm%20rpo%20differential%20codes.pdf

There is a lot of conflicting info out there as to whether synthetic 75W-90 oil that already contains limited slip additive is sufficient or whether you also need to add the LSD additive in the rear diff on these units with the G80. I did not add any additive in the front diff since there is no limited slip components. But the rear diff I was not sure so I added it.

LOCKING DIFFERENTIAL LUBRICANT (SERVICE INFORMATION) #91-4-109
SUBJECT: LOCKING DIFFERENTIAL (G80) LUBRICANT - (SERVICE INFORMATION)
VEHICLES AFFECTED: ALL LIGHT TRUCKS EQUIPPED WITH G80 REAR AXLE ALL YEARS
Some light duty trucks equipped with locking rear axles (G80) may exhibit rear axle chatter, especially when turning a corner from a stop.
This condition of alternate engagement and disengagement of clutches in differential assembly is usually caused by contaminated axle lubricant.
To correct this condition, drain and refill the rear axle with SAE 80W-90 GL5 (P/N 10950849).
The use of any additive in locking rear axles (G80) is not recommended. Rear axle additives are designed for use in limited slip differentials which are normally installed in cars. All light duty trucks equipped with RPO G80 make use of a locking differential and the use of additives will delay the engagement of the locking mechanism and may decrease axle life.
VEHICLES/COMPONENTS INVOLVED: ----------------------------- Some light duty trucks equipped with locking rear axles, RPO G80.
SERVICE PARTS INFORMATION:
Part Number Description ----------- ------------------ 10950849 Lubricant, Rear Axle (1 litre)
Parts are currently available through CANSPO.
WARRANTY INFORMATION:
As specified in Light Duty Truck Maintenance Schedules, locking rear axle fluid drain and refill is required owner maintenance at the first engine oil change. Failure to drain and refill the rear axle as specified may contribute to a later axle chatter condition. Refer to the appropriate Light Duty Truck Maintenance Schedule or service manual, section OB, for further details on change intervals.

Thanks for the info! Darn I guessed wrong. I added additional LSD additive to the rear diff. Guess I will be draining it and refilling without additive. There are a lot of people out there claiming that although the G80 says it's a locker, that it was actually a style of LSD and therefore needed the additive. But this GM bulletin is pretty clear that the additive can make it wear out faster.

Just posted a new video on gear tooth contact patterns. Any of you with any real world experience setting up differentials know that it is more of an art form than a science, but I hope this helps clear up some general questions.
-
Just added a very relevant video I should probably link to the DMAX forum on how to identify which GM 14 bolt differential your vehicle has. I'm sure newtomegmc would have something to say about it, but it should answer any GM 14 bolt related questions between identifying the 9.5, 10.5 or the 11.5". Any feedback would be appreciated.
-
I did a search with 14bt and newest vids from randys, nothing. Linky
-
its in the very first post JR, video #17.
tater, I cant say to much about DF as I have not been there but to check in on 1 thread in almost 2 years. I got sick of the childish garbage that was going on over there.
-
I watched it (thx for the link) and a few others. I do think when you talk about how to ID a diff, you should show the cover too.
I have set up several rear ends, no expert and probably not any as good as anyone who does it for a living, but not scared of em.
I hear what you mean about forums. Many end up that way.
-
I agree on all counts. I think that I will try to incorporate as many items in the future as possible to help with tech, because honestly, I've been doing this for so long I just take for granted that what I know the avg. person knows too. Yesterday I had a customer ask if I had the little spikey round thingy that the long metal piece the wheel is connected to goes through. Took me a few minutes to explain axle side gears, or even the concept of spider gears. She was calling for her husband who I could hear hollering at her from the next room. I told her she could put him on the phone if she preferred, but that seemed to make her nervous. Strange folks, but it reminded me even the simplest things sometimes need explaining.

Just added a couple new videos on positraction install, and locker operation FAQ(s).

Wow, it's been since April since I put another one of these up. Top of the list there fellas. Chop saw and specialized tool fun.
