Hummer H3 Transfer Case Pt 2

[@sapphirejan2040]

Thanks for the video. I dropped mine off yesterday to the transmission shop and I'm anxiously waiting on their phone call to see how much this job is about to cost me. It was really nice to be able to see and understand the issue and everything involved.

[@Snailmailtrucker]

Do you remember how much that they wanted to do this job ?

[@sapphirejan2040]

@@Snailmailtrucker The transmission shop ended up giving me the great news that my problem was not my transfer case. The repair shop had misdiagnosed the problem. All I ended up needing was a front differential mount.

@@sapphirejan2040 Excellent... good news for a change ! Appreciate your reply !

[@Snailmailtrucker]

I appreciate your taking the time to create this video... I am disappointed that you didn't even show us how to remove or reinstall the actual defective Shifting Fork. One minute the defective fork is there and then in Part 2 the fork is installed. Thanks... I think !

[@Snailmailtrucker]

After completing the transfer case shift fork replacement... I am happy to report that my 06 H3 rolls freely now and I am getting about 18 mpg city now, up from about 13 mpg with the drag from old fork not functioning properly ! No more drag at slow speeds at all ! Pain in the ass job but well worth it !

[@diymechanictv1233]

Glad your project was a success!

[@melissalee4446]

Just did mine today. Your guide was super helpful! Thank you. How did you replace the output seals?

Glad you found it helpful!

[@garnerbiker]

Thanks for putting all this together. Doing mine this weekend.

[@rizkybiss]

Saw your video and it is very intuitive. So it looks like I have the dreaded broken plastic shift Fork. Am I able to open up my transfer case myself, and just change out the plastic shift Fork to metal without disturbing anything else and put it back together. I don't want to mess with realigning the planetary gear or anything if possible.

[@diymechanictv1233]

There is a chance you'll need to realign the planetaries when the case comes apart. To be honest, it's been long enough now that I do t recall whether the planetaries came apart when I split the case or if I separated them for inspection, but if lining them back up is a deal breaker for you, I'd suggest letting someone else do the work. Thanks for watching!

[@20tea]

There are timing marks on the planetary gear set. There is more information about this on other youtube videos.

[@danielraymadden]

Good video. My H3 just started having a binding turning right or left. Feels like brakes are on. Makes a rubbing sound, thought it was brakes. Stiff does not want to move on turns. Your vid popped up the next day. I wonder if google can detect the sounds of my car ? Your video is simple informative, is their a full replacements parts list for reman transfercase ? Does GM Delco have an alloy fork ?

Does the chain need to have some slack or does it have to be really fitted

[@arebonbali2089]

thanks for the nice video. I do have questions please. for the last 1 and half month ago I accidentally was driving with 4WD high lock. must be my hand touching those botton while I'm cleaning the interior. so what happening is, every time before park with Sharp turn right either forward or backward in parking lot, I have hard time because the vehicle won't move and make some noise so I went to straighten the wheels and backing up with no proble m. I call my friend telling him what happening and he said something to do with the 4WD. so I check the bottom and I notice it's was for a while (1& half month I have been driving 4WD high lock. ) so I make switch to normal 4WD regural. and everything sound back to normal except the noise coming on and off only when I driving slow sharp turn in parking lot. my question to you is : did i broke anything in the transfer case or not? what are the noise you think? thanks for your help and advice.

[@TerrySmith-em4ph]

So if your timing marks are not lined up what do you think would happen ???

[@evelyntirado3054]

Hi. Hopefully you see this in time. My '06 H3 stopped functioning while my daughter was on her way to work. So I went to where she was at and got in my truck. Turned it on and went to go reverse, it sounded like grinding but not technically a noise to hurt the ears! I asked my daughter if she went to drive it to pull it off road and she said it made the same noise. So at this moment, I am about to get under my truck and see how much gear oil I have in my transfer case. However, from watching part 1 of your video. I am leaning with thinking I may have to take the whole unit out. Are you familiar with any sounds that come from the transfer case?

[@diymechanictv1233]

Hey there, I have heard a similar sound before when the transfer case slips into neutral. It's possible that the chain in the case broke, but it's also possible that the fork I repla Ed in this video failed and the case is between 2wd and neutral. Try shifting it into 4x4 and see if it catches and will move. At any rate, somebody needs to check out the transfer case. Good luck!

[@nickc7039]

Wow your the man. All the GM part numbers much appreciated. Have you ever heard/ dealt with modifying the case to be selectable 2wd?

[@diymechanictv1233]

Glad you found the video to be helpful. I've never heard of modifying the case to be selectable for 2H, but that would be a cool feature if it's doable. I'd imagine it would involve changing some "hard parts" to incorporate a split shaft and locking collar.

[@danielavila6086]

How long did it took you to complete this job? In terms of hours.

[@jonathan_beattie]

I've got a bad encoder motor. It will not shift. Took old one off new one on. Tried to shift. Says service 4wd. Note this is after getting it back from the shop having the fork replace. Any tips would be helpful.

[@diymechanictv1233]

If you had a shop do the repairs, I think you need to talk with them about making it right. Even if the encoder motor was bad when you took it in, you have fixed that issue and still have a problem. How could the shop have verified their repair if the system was not working?

[@charliecrowe1644]

Why did you have to mess with the gears if I pulled mine straight apart wouldn't it go straight back together without messing with the gears let me know please

[@diymechanictv1233]

Yes it should as long as nothing gets moved or bumped.

[@davidharvey6253]

@DIYMechincTV. I get a vibration when driving above 2500 rpm. Was thinking i needed to get my drive axles re-balanced. Took it to the shop and that wasn't the case. They showed me where my rear axel went into the transfer case and was a little warped. They believe there was something wrong with the transfer case but did not have the expertise to fix it. Do you think it could be the same nylon fork that you mention in your video? Would that cause vibration when driving?

[@diymechanictv1233]

I don't see the fork causing a vibration while driving. That does sound like something out of balance.

[@davidharvey6253]

@@diymechanictv1233 I did take it to get checked out by an axel place and they told me both my front and rear axel was fine. However they did show me where the yoke of the rear axel went into the transfer case had some grooving on it. I have a pic but cant and it here

[@davidharvey6253]

@@diymechanictv1233 I just really want to make sure that there isnt a major issue with my transfer case. I just put alot of money into it getting the engine rebuilt

[@diymechanictv1233]

@@davidharvey6253 I don't see where this issue would be associated with the transfer case. I would attempt to determine whether the vibration is related to engine speed or to ground. For instance, if you lock the engine into a different gear and go above 2500 RPM and you feel the vibration reagrdless of what the ground speed is, then I would look at the engine as the possible source of the vibration. If it is related more closely to a specific ground speed (MPH) and is there even if you change the gear selection of the transmission (like taking it out of overdrive) then I would look at driveline components or even a tire imbalance/tread separation, or something along those lines. Knowing whether it is tied to engine speed or to vehicle (ground) speed tells you which way to approach the troubleshooting.

[@davidharvey6253]

@@diymechanictv1233 thank you for the insight. I can tell you its definately more related to ground speed. Mainly about 50 MPH. I will check for a tire imbalance for sure. Other than that, what else could be the issues with a driveline component? Would you mean wheel bearings possibly?

[@hondabri277]

Hi Great video, I have a problem with my Hummer think it could be this. I was reversing and something popped had no drive forward or backwards. once i got the vehicle jacked up realized the e-brake had seized on could this have caused the fork to pop and maybe put the transfer case into neutral hence no drive. Its a standard transmission?

[@diymechanictv1233]

Sure sounds like an issue with the transfer case to me!

[@richardhargis420]

I followed your video and all went well except the shift motor shaft. I cannot install the shift motor onto the shaft and the shaft has limited movement so I think I messed up when I put it back in.

[@diymechanictv1233]

It's possible that the case is not in neutral (or in whatever position the motor is in). See if the shaft will move freely if you move it manually (using a pliers or similar). If not, then I hate to say it, but you may have to pull it apart again and see what isn't aligned correctly.

[@EDGAR15ish]

@@diymechanictv1233 what do you mean aligned correctly? Im about to pull mine and I dont want to mess up also what type of seal did yoy use?

[@diymechanictv1233]

Just be careful when you put the shift motor back on that you get the motor aligned with the shaft so that they lock together correctly. For the seal, I just used Permatex Ultra Gray silicone sealant.

[@rizkybiss]

Got a question for you. Is there a viscous coupling in that transfer case?

[@diymechanictv1233]

Not in the one I took apart! It's all solid.

[@rizkybiss]

Yeah I didn't Think so. I have the 4494 And I took it to a mechanic 2 days ago. He swears the problem is the viscous coupling and I was telling them I don't think it has one and to just rebuild my transfer case.

[@minidonutworld9789]

Hello. Would love your input. I cannot find anything that pertains to a timing on the transfer case. Where did you get this info from?

[@diymechanictv1233]

It's been a long time since I made this video, but as far as I can recall, I had to figure this out by trial and error. If I remember correctly, it would only fit back together one way.

[@Chipster1337]

Would it be possible to view the shift fork from the fill plug? Trying to figure out if I have a plastic fork or aluminum. From the exploded parts diagram it looked like it might be possible but Im not really sure. Im not familiar enough with the orientation of the parts in there.

[@diymechanictv1233]

I'm not sure if you could see it or not, or if you could, whether you would be able to tell if it was nylon or aluminum. A cheap bore scope, might be the way to go! Grab a USB bore scope and let us know what you find! It might just save you a few hours' time.

[@loridaniels9452]

What might be the average cave man Dan turn around time on a project like this IF one gets the fork and screen ahead of time?

[@diymechanictv1233]

It's really not all that big a project. The labor can be done in a day without a lift and with the use of just basic hand tools. Allow a weekend if you're not an avid mechanic, but it's really not a difficult or complicated project.

Can anyone tell me what is the easiest way to put the 2 halves back together? Do you have them side by side or the half with the gears facing up and the 2nd half coming down from above ? I'm having a terrible time getting the shift lever, the Fork tube, and the 2 drive gears to align up to the second half of the Transfer case !

[@305-Dinguez]

Hi, does anyone know if I can just replace the shifter fork without removing any of the gears ⚙️? Thanks

[@diymechanictv1233]

It's been a long time ago since I did this job, but I don't think the fork can be replaced without removing the gears. I don't think you can access it until the gears are out of the way.

[@NIA-nv8wg]

in D it is very strong and it is very heavy, it almost does not move, I put the accelerator to the bottom and it moves but soft until it takes speed and walks normally. in R walks perfect. It does not have any noise when walking. turn on perfect. I would like your help before spending money. I hope someone helps me. Thank you. 2007 hummer h3

[@diymechanictv1233]

If the vehicle won't move in a straight line, I don't think your issue is the transfer case. I would look at the braking system or the transmission based on the symptoms you describe.
