    ‘99 Exp 5.4 4X4 no heat?!?!

    I second blend door actuator. If you had the front heater core replaced and both tubes from the heater core are hot, its got to be something stopping the blend door from switching to the hot side. It may not be the actuator itself (but that's where I would start) but its got to be blend door...

    No 4x4 Low Indicator, No Actuator Movement 97 Expy

    Yep, I think I used the same thing. It was pretty simple. The hardest/most annoying part is re-pinning the harness, but as long as you get that right it is pretty straightforward.

    No 4x4 Low Indicator, No Actuator Movement 97 Expy

    Are you in neutral when moving the switch to 4Low? That seems obvious, but I've made that mistake before - the truck will allow you to switch to 4x4 while in gear, but 4LO specifically you must be in neutral for it to work. You mentioned the bulbs. My '99 has a 'LOW RANGE' light that comes on...

    Removing Roof Rack 2001

    Try soaking them in PB Blaster for a while before removing them. Fortunately, all the torx bolts on mine came right out no problem, but I am in AZ so rust isn't really an issue here.

    Removing Roof Rack 2001

    It was very simple, in my experience on my '99. The front crossbar has a fastener on each side that you're able to unscrew with your hands, then you can lift it straight up and out, pulling towards the rear of the vehicle. The rear crossbar I ended up leaving attached to the rails, unscrewed...

    Wheel bearings? Rear diff?

    Here you can see the wear on the axle shaft. And here you can see the dent that somehow got put into the axle tube housing. I heated it with a torch and tried to hammer it out a little bit and also hit it with a die grinder. This whole job on both sides was quite a chore. Almost wish I...

    Wheel bearings? Rear diff?

    I do think it was a bit of a case of howling rear diff. However the vibration is what I am really hoping to solve with wheel bearings. That and the fact that i'm not sure if they've ever been changed on the truck and it's got about 210k miles on it now. I just got done replacing wheel...

    Wheel bearings? Rear diff?

    Thanks all! My gut is telling me it is rear end (though I could be wrong). I just need to decide if I want to save some money and just do the rear wheel bearings/seals and hope that takes care of it, or if I want to get crazy and put a TrueTrac back there while I have the diff open... Another...

    Wheel bearings? Rear diff?

    A little info on the truck: it's a '99 A4WD 3.73 w/ LS I've had a mysterious howling/roaring sound for years that I honestly have a tough time hearing if it's coming from the front or rear. It's also accompanied by a vibration at highway speeds, which I always assumed was from crappy...

    Idle problems

    Unfortunately this is a tough one, because it could be many things. Check all your vacuum lines first. Sometimes rubber boots split or become too weak and cave in under vacuum, or the hard plastic lines crack. Check the bigger hose at the very back of the intake, towards the firewall. If you...

    Weekend Sedona Adventure

    Can confirm. I had my wife and 4 year-old with me, that was a mistake :Big Laugh:. If I do that trail in the future I would definitely start at the top, coming from the highway, instead of starting in Sedona. Hindsight...

    Weekend Sedona Adventure

    I can appreciate those features on newer vehicles. With a 20 year old truck I find myself wanting even less electrical features, even the basic electronic 4WD systems (especially A4WD) on these seems to be temperamental. It's sometimes even tempting to swap over to a manual t-case IMO...

    Weekend Sedona Adventure

    Took a last minute trip up to Sedona. Decided that since I just replaced the shift motor it was time to put the 4x4 to the test, so I took the Schnebly Hill trail from Sedona out to highway. The truck did well, though I should've probably taken some air out of the tires. VERY rocky. I think I...

    My 99 Expy 4x4

    Bob - If you get the flashing CEL, a code reader should pull a code even if the CEL isn't staying on the dash. If it tells you a specific cylinder misfire, there's a good chance it's the coil pack on that plug (COP). I'd start with swapping the COP and maybe the plug while you're in there. If...

    My 99 Expy 4x4

    Fortunately they're still in good shape Jim, i'll definitely reach out to you at some point to make that happen! It might be later than sooner as I don't get too many days to myself, but I'll make it happen. I've lived in AZ all my life but never really done the offroad thing with the...

    My 99 Expy 4x4

    I'm a big believer in bringing tools along also, never know what might happen! I do need to look into a high lift jack though, and fire extinguisher. Supplies are just as important as mechanical upgrades for sure.

    Transmission Coolers Install

    Jim - I've also thought about a double din head unit, you're right though the good ones do get expensive. Maybe something down the road. Tom - thanks for the suggestion, i'm going to look into the UltraGuage also!

    My 99 Expy 4x4

    Hi all, hope i'm not double-posting - don't think my first post ever showed up... Anyway, I own a '99 Expy, 5.4l 4x4 here in Phx. I've used these forums countless times over the years, as I've made countless repairs in the ~9-10 years I've owned it. Recently made the decision to start putting...

    Transmission Coolers Install

    Jim - what are you using to monitor your trans temp? I'm considering getting the ScanGuage II, but open to suggestions... I like your dual Haydens. I just installed a 6.0 cooler over the weekend.
