:ditto: Thanks, exactly what I meant.

Unless you've done it already... There are 1" spacers on the transfer case mounting bracket. From the factory they are on "top" of the bracket. I usually move the spacers to in-between the mounting bracket and the frame. I've done this in the past with my Blazer's with a 4" suspension kit...

I also had a low power issue on the M1009, but have finally fixed it. My truck had the white smoke, low power, etc. I had two problems I believe. The first issue was the filter in the fuel tank. It's a small "sock" type filter connected to the fuel pick up line. Mine felt almost like a...

I installed a new to me vacuum pump, now were producing 20" of vacuum. So I've fixed one problem only to find the vacuum pressure is not going thru the switch on the IP. There is no vacuum pressure at the top port of the switch, but a good 20" coming in directly from the vacuum pump. Can the...

I was finally able to test the actual vacuum at the pump, it fluctuates of course, but it only produced about 5" of vacuum. Hopefully I've zeroed in on the problem...with you tips of course. I've removed the pump for repair/replacement, and I want to say I remember reading that these pumps can...

I thought that to, but I figured by running a direct vacuum line to the modulator from the vac pump it should eliminate that as a possible problem..?

I believe the lights are sealed, and would have to be replaced as a complete unit. I don't know for sure where to find new ones, but I would be very interested as well. I have a few with broken terminal ends. I'm sure someone here has an idea. Andy

I'll pick up a vacuum gauge tomorrow hopefully. I agree I need to verify the actual pressure at the vacuum pump then go from there. It's an expensive part to just go by "feel"! The modulator is new, but you never know, it wouldn't be the first time a new part didn't work. Thanks for the...

Hi everyone, I'm working on a 86 M1009 with a hard shifting problem. I searched the many posts and have tried several of the suggestions given, there's lots of knowledge here. This is where I'm at so far. -vacuum lines are all new, double checked the hard line to the modulator, even ran a...

I believe my truck has the relay replacement, but I will look into it to make sure. I'll get some pics soon as well, she's in the garage while I'm going over everything. Thanks for the tip, and everyone taking time to say hi.

Hi everyone, finally wanting to say hi, and thanks for all the useful info so far. My name is Andy, from the south west Michigan area. I've recently picked up a M1009 and have found a ton of tips from everyone here. I'm sure I'll have questions in the future, just wanting to get my foot in...
