What did you do to your GMT today?

Trailblazer and Envoy related, but not off-road related...

Thanks to the guys here, I purchased two spare CV's from Detroit to go with my two spare hubs. Still wondering what other spares I should have for the trail besides a possible tie rod which I don't expect to need, but one doesn't know. Guess I need to look thru some more threads to see what else has commonly failed off-road.

I had totally forgotten about the 4WD selector switch till you mentioned switch! Here that goes out. I'm hoping that by Aug, Alex will be travel worthy. I think this year we're going to do more of roadtrip than off road trip, but I plan on heading back out west in August. So I'm making a list and checking it twice. (dork)

Stick your giant pry bar screw driver up through the slotted hole in the LCA bracket. Put the tip behind the inner tripot. Smack the handle of the pry bar with a BFH, using the LCA as your fulcrum. A couple good hits should pop the C-clip. Make sure you load the spline up with anti-seize to make it easier to remove in the future.

Mike, why do you need two hubs and two CVs? Seems like a lot of extra weight for something that works on both sides.

Same thing as a UCA... you only need one since they are somewhat "ambidextrous". And since we've seen two UCAs fail, I'd add that to your list. I used to carry one around.

Crap James, way to spoil it. :wallbash: I didn't realize the CV's were interchangeable. Online it was listing them as passenger side and drivers side, I guess that was an amateurish mistake on my part, or maybe proof I shouldn't order crap at work when I can't look at my truck.

The hubs I ordered just came as a pair, so that why I have two, but I can always leave one in the garage.

After my hub failed, I would carry two so even if you swap one you'll still have a spare. CVs I carry one and I didn't think about carrying a upper arm.

Hubs don't fail instantly though. You should have a good amount of warning when one of them fails. If you do have to replace one in the field, once you get back to civilization, your first thing should be picking up a new spare. But I've NEVER heard of two hubs failing in one off-road trip. Maybe you'd need two if you were going through the Sahara or something.

Well if youre going to spend a good bit of time of road then 2 spares are reasonable

There have been more front n rear springs collapse than UCA fail so prolly need spare springs. Sucked driving back from VA w shit rubbing on every bump.

Same here, very effective and inexpensive to boot. I got the slide hammer from pep boys boys and the attachment from autozone.

Just used mine today to toss in another cv shaft, also found my front pinion seal is leaking... Awesome!

But there's a big difference between a broken UCA and a collapsed spring. You have to take severity into account.

You can drive a very long way with just a collapsed spring. Sure it may suck, but you made it all the way back home without issue. You can't drive far at all with a broken UCA, and there isn't a very good trail fix for it. The fact that we've seen two UCAs fail soon after being off road is just straight-up luck. Had they failed while off road or off-camber, those people would have been SOL.

Slowly and surely getting things put back together. I can't believe it took 20 minutes to press in one freaking ball joint! These Moog ball joints look pretty nice however.

Thought I had a noisy tensioner pulley so I replaced it and the belt. Nope... noise is still there. Thinking it must be the water pump bearing. Hard to localize the noise though. I'm not looking forward to replacing the water pump. Such a messy job.

Doesn't look fun James, was just looking at that yesterday since I'm going to be removing the Alternator which doesn't seem fun either. And my belt is a bit old, so I think I need to replace it plus the tensioner for good measure. I had no idea until recently that the tensioner is a wear part with a shelf life. At least GM claims so.
