Ball Joints
Outer Tie Rod Ends
Rear Washer Pump
LIM Gaskets (on new engine)
Replaced Knocking/ Locked up engine
Light bulbs in Stereo faceplate
Installed an aftermarket remote start because factory RKE was toast
(I am not worried about maint stuff like plugs/plug wires.)

On our 99 when we had it:
1. LIM gaskets (under warranty) around 26k
2. Water pump around 90k
3. Cracked exhaust manifold around 150k

On our 04 we have now:

Nothing, van currently at 76k.

2002 Montana 117k:
A/C condenser - Bad when I bought the van at 80k. (dealer paid for the condenser, I put it in)
Broken exhaust manifold studs 2 on front manifold luckily. (I think they may have done head gaskets on this van and overtightened the manifold bolts, they also left the egr pipe out of the rear exhaust manifold (sounded loud, but got great mileage: over 30mpg)
Right Front Hub, left rear hub (lr was ABS issue, RF was bad bearing) I noticed now the LF hub bearing is loose. No noise yet, but will be replaced soon.
Radio lights
Rear heat temp door motor

That's all I can think of right now. Overall, easy repairs and a better riding, driving and stopping van you will not find. I drive and repair a lot of different vans for customers of mine and I have to say the GM line of vans is by far the best driving/riding of them all. Not necessarily the easiest to work on (that goes to the Dodge caravans of the early 2000's) but the rest makes up for it.

Yeah, plugs on my mother in laws Caravan 3.0l were a PITA.

I do like working on the Chev stuff over the other brands, maybe I am more familar with it (I grew up in a Chevy Dealership). I love the way mine handles/ drives after the ball joints and tie rod ends that I had to replace, but it is always something (241k miles). :-)

Lamps for the radio, takes about 10, so 5 packs would get ya, I had to replace some in my HVAC control head also, about 8-10 there also.

Thanks Lesterl. Had the radio out once and tried to get the faceplate off, couldn't really figure it out, didn't want to break it, so I just put the radio back in. You have any instructions to remove the faceplate from the radio body?

Ya gotta pull the top of the radio off, pull the nutts off the tune and vol knobs, pull all the knobs, pull the wires, pull the few screws holding on, then you have to pull a bunch of very small screws with like 4.5mm heads out of the board to get it off the faceplate.

P.S. may be a few things left out as it has been awhile..... If I ever do another I will post a writeup.
