Ok, got a 2006 H3,200,000 miles, I love this truck, fun to drive, previous vehicle 2000 jeep xj. feel like this was the next step. So, that being said I've had typical problems nothing major. except an oil leak in the manifold gasket. had that fixed coil packs, plugs, wires, replace the fuel intake to fix minor error codes and rough idle. Now having some transmission issues. going to have that fixed. I have about 5-6 grand that I'm willing to put into this truck after the transmission work if I can get another 100,000 miles out of it. could have put 10 grand into a used truck but I love my Hummer and I know it, as opposed to buying a used truck I have no history with. going to do some suspension work control arms, shocks, bushings. What I need is advice on is, what should I do that would give it the best chance to make 300,00 miles short of putting in a new engine. Thanks for any response.

 

About the only in class replacement would be a Jeep Gladiator/Rubicon. With all due respect to JL Jeep owners, I can honestly say Jeeps are junk my JL was a complete POS. I too feel as you do, I would rather dump 20k in my 08 H2 then to buy a new Jeep or GM with their transmission engines.

Most of the new stuff is turbo'd 4 cylinder sewing machine engines and loaded with electronics which will be nightmares when they go out of warranty.

There's a lots of options, crates can be gotten under 4K, transmissions can be gotten under 3k, suspension parts are cheap, you could do a complete chassis rebuild under 1500 including a new steering box.

If your H3's body is rust free in good condition this actually becomes a no brainer. About the only concern I have is a major accident, if that happens the insurance company will put the screws to you and give you nothing saying repair parts are not available. Something to consider.


We have lots of H3 experts on this forum that I am sure will add to this thread, best of luck with your decision!

 

 

I agree about the jeeps, I bought my xj for 2000.00
put about another grand into it. Lifted a bit new wheels a little engine work. I did love driving it. When the transmission went out I was not willing to dump several grand into it. I feel the same about the other jeeps. I belive a complete suspension is a very good idea.

 

A Trans Rebuild does not cost $5K. If you have a reputable local transmission shop, you can have them rebuild it better than new with some select aftermarket improvements, like a Beast Sunshell etc...

Like my Grandad used to say, if it ain't broke, don't fix it.

Can't tell from your post if you are doing the wrenching or paying others. With a truck that old, buy some tools with your buget and learn how to do what needs fixin yourself.

Welcome and good luck.

 

No I'm not paying 5k for a transmission. I have an additional 5k that I can put towards other things to get another 100k in miles out of it. I do some minor things, and most of my own mods. I do not feel comfortable doing anything major. My Hope's are to get advice on what could be done while the transmission is out and avoid future major repairs.
Right now I'm looking at transmission and suspension work. I have a great garage that I'm taking it to. It's a bit of a haul but these guys do phenomenal work. I Trust them not to steer me wrong. I have had them work on several cars and they always exceed my expectations in quality of work and price. Beats local garages closer to me by several hundred of dollars.

 

OK. Just like you cannot pre-shovel snow off your driveway before the snow storm, no point in fixing stuff you think might break before it does.

Depending upon the last time you changed fluids, I would change the Transfer Case fluid, front & rear diffs, coolant and flush the brake fluid.

Check the flexible brake lines for corrosion and fraying. Check the front diff bushing for excessive movement. Check the lower ball joints for slop if they are not chirping for attention. Check the U Joints and front drive shaft CV (at the TCase end) for excessive wear and movement. Replace if necessary.

Drive and enjoy.

 

Solid advice. just wasn't sure if there was anything to check with the transmission already out of the truck.

 

Great line there... Can't pre shovel...lol! Never heard that.

 

The H3 is a solid frame shared with GMC Canyon and Chevy Colorado with a few extra crossbars for strength.

This provides a good platform for you to work from. Like a firm foundation on a home. If you treat the rest right you will be fine.

200k on the od with good care may not be a show stopper. So like others have stated here. Focus on the basics, and enjoy!
