So I've talked to Firestone and Les Schwab about replacing the brakes on my M998A1 and as soon as I tell them its inboard disk brakes they won't touch it with a 10ft pole. Any one know some major auto repair shops that would replace brakes on a humvee/hummer h1? Any in the Seattle, WA area?

First Problem: When I brake, I can hear a whining sound and with hard braking the pedal starts vibrating a decent amount. Second Problem: Recently I took off old goodyear tires and replaced them with BF Goodrich tires (same size, load range) to match my two front tires. I did keep the old 12...

So I was looking into converting my old M998 to a HL80 transmission to help with gas mileage and speed, but then I found the H-line conversions. As I saw on their website, its a 500 HP upgrade and 25 MPG for the bio diesel system they put in. Now I do not know much about bio diesel systems...

So I cannot find anywhere what the difference is between an M998 and the A1 version. I notice the weight of the vehicle was increased by 180 lbs. So what did they add? Also, I saw that 1982-1993 humvees and hummers used the 6.2 NA, and 1994-2004 that its all 6.5 NA's and Turbos. So my vehicle...

So I finally got to replacing my old horn (old horn was very quiet, couldn't hear it over the engine) and I bought a new horn from eBay. I plug it in and test it and all I hear (engine off) is a decently loud clicking sound. I thought maybe the plugs are backwards, so I reverse them. Same thing...

Anyone know where to find the last remaining slantback kits? If I decide to setup my vehicle in a GMV config, where would I find that special forces GMV C pillar for the turret roof? Has anyone ever done a GMV setup? and if so what did you use as a divider between the cab and the now exposed...

i was going to replace my steering wheel and took off the horn and the nut while pulling upward I hit the center with a hammer. Didn't budge. I stuck wd40 down the threads of the center and waited a little, tried the same thing again. Didn't budge. By this point I'm frustrated so I try sawing...

I have a 1994 M998A1 with a 6.2L NA and I am looking to start the big project of swapping the 3L80 for the 4L80. I've started my initial research and saw some discussion on the list of things that need to be done and it is quite long, but some were saying that its better to upgrade to a 6.5l and...

So I took a trip in my humvee over a mountain pass to a town about 80 miles away (chuggin along at 50). Before I left I checked the tire pressures and they all were inflated correctly, taking note that the two rear tires were a little low. I get their, I do what I need to, then I come back home...

I am looking for information regarding any fuel injector upgrades to get for an old humvee to increase the hp.

I recently went on a small trip out to a off road trail and it was a 30 mile trip out on a small highway, I kept the RPM down below 3000 and around 50 mph. On the trail after two uphill trudges, I stopped to take a look at a nice view and came back with a moderate amount of white smoke that did...

Are there any military vehicle scrap yards that one can visit and purchase parts from? I think I've heard of them but I don't recall them being open to the public. If a scrap yard were open to the public, does anyone know if there are any near Seattle?

I have a tachometer that is an alternator sensor one, and I cannot get it to register the rpm I bought the kit on ebay which has the cable that goes to the fuel gauge then out to the alternator. I think the part going out to the alternator is the problem, I hooked up the plug to the outgoing...

So I have this '94 M998A1 that currently has a tachometer sender installed and appears to be wired to a diagnostic connector right above the transfer case shifter. In my case, where would I need to start with finding the wires to hook up a tachometer? Side note: the windshield tachometer...
