I have a 2009 H3 Adventure. I've had it for two years. So far I replaced original BFGs with T/AKO2s, new radiator, new rotors and pads, a new wheel bearing, new shackles, just received new leaf springs, u- bolts and also pinion seal and having those put on this week.

Our driveway is on an incline and I never have this problem starting it anywhere except when I fill it up. When I do every now and then it kind of lurches forward a bit. What could this be? I'm tired of pouring money into it.

 

Actually, all of the things you listed are normal wear and tear for H3's. I've done many things beyond this.lol.
Do you have a code? Do you have a scan tool?

 

Your second paragraph confuses me. I'm not sure what you mean by "lurches forward" a bit, nor the statement about an incline, starting up, or after a fill up. As for your repairs, obviously brakes and tires are normal wear items.. As for the others, how many miles do you have on it?

 

Sorry about the confusion. This never happens when I start the truck at home on the incline, or anywhere else on flat ground. This happens only when filling up. It is like the truck jumps a little like I just put it in gear, but it was in park the whole time. I have 105K on the truck. I have put 50k on on it. I'm guessing whoever had it before me didn't do much maintenance.

 

Why would you need to replace the shackles?

 

Buy one of those cars that never require maintenance and run forever. Oh wait, nevermind, they haven't invented one yet.

Other than shackles, everything over 100k is normal maintenance items for an H3.

 

Radiator?? not normal maintenance.

However, your point is a good one and well taken.

 

Update: I ordered the leaf springs from GM Parts Direct. They came and I had them installed. I had previously replaced the shackles because they were badly rusted and pieces of them were falling off.

I got the new leaf springs and U-bolts installed today at a different shop. The first shop I went to made an appointment with me to do the work but then refused to do the work when I showed up, telling me they couldn't fit me in for a few days. No thank you. I'm done.

Since it was on the lift I also had the new shop replace the leaking pinion seal.

Here's what I found out - thank God I had the job done. Not only did I have a broken leaf spring I also had broken U-bolts. The axle could have slipped and done major damage. The new place I went to today was great. They were polite, professional and the shop was pristine. The price was right too!

Lesson learned: do the maintenance with a reputable shop and don't put up with shoddy service,
