    NBS/Astro knuckle brake upgrade.

    Thanks for the suggestion I saw a link posted a while ago that has since gone dead. Not sure which ones on there now are reliable and the ones I have recently found all say for cars only, not trucks

    NBS/Astro knuckle brake upgrade.

    The Autel MaxiCheck pro scan tool WILL NOT perform the ABS function test on GMT400 It does not have the ability to communicate with the Kelsey Hayes module Looks like I am going to be shelling out the BIG bucks for a Tech2

    NBS/Astro knuckle brake upgrade.

    The valve on the ABS unit is now stuck out and won't budge. That is how I found it with a bit of fluid inside the black cap Maybe that has something to do with my issues Hopefully the whole module isn't wrecked I just ordered the Autel MaxiCheck pro scan tool because it can supposedly run the...

    NBS/Astro knuckle brake upgrade.

    Worth a shot. The truck is still on the lift. I have not even put it in gear since starting this upgrade conversion 8 months ago

    NBS/Astro knuckle brake upgrade.

    My thought process is leading me towards the ABS unit having something gummed up and needs to be run with the fancy scan tool OR the combination of AC Delco GMT400 master cylinder with Rock Auto vacuum booster has something out of whack. I bled the Kelsey Hayes unit as much as possible with the...

    NBS/Astro knuckle brake upgrade.

    I finally got everything installed and swapped over on my truck It is still up on the lift, but I have run into the strangest issue The front calipers spun completely free at first and everything seemed great Now the two sides alternate building pressure and locking up after releasing the brake...

    NBS/Astro knuckle brake upgrade.

    How did you make out with this swap? I ran into that terrible roadblock that is Winter before being able to complete all the work on my truck. What did you manage to do for the brake line fittings? -Kevco

    Lets's talk Corrosion, a.k.a. Rust!

    The bane of my existence! I can feel my truck crying as Fall comes to an end every year and the salt monster comes back for another bite. But after seeing how bad those rockers, or yet lack there of, I feel my truck is actually still pretty sturdy considering

    Dual Exhaust Question

    How was the dual exhaust mounted on your Suburban? I have always wondered if you could make it work and I also dropped in a 383 But the 43 gallon tank, torsion bars and crossmembers made dual pipes too tricky

    1997 K1500 Suburban vacuum diagram

    I never drove my truck with the stock motor on the road, only to get in around the yard and into the garage. My HT383e was only $3400 (I think) since I had a commercial loading dock to send it too for GREATLY reduced shipping costs. I bought it as the "Truck re-power kit" from GM and they call...

    1997 K1500 Suburban vacuum diagram

    I had been looking to see what I was able to find for manuals. I saw posts linking to downloads here as well. But 1997 is a ******* year of GM mix and match or one off configurations it seems. I have not been able to find that specific one, always missing on everyone's list. Finding 95 & down is...

    Suburban down.

    I am running that ht383e GM truck re-power kit crate motor in my 1997 Suburban and it works great for me But I got it over $2000 cheaper than that Though Im not sure how it compares to the stock 350 since I bought the truck with a blown engine

    loud unkown clunk or pop after towing. front axle?

    Sorry to kinda hijack this thread BUT do you know if having the electronic actuator on my 1997 Suburban makes my front diff a 1st or 2nd design? I need to replace worn axle bearings and mid-97 was apparently split production The different designs do not use the same size bearings and seals...

    1st vs 2nd design IFS?

    Using a couple of the VIN decoders posted here, I found that my truck was manufactured June 9th 1997... Which runs smack in the middle of where they have been saying the cut off is Dammit this rabbit hole is a DEEP one

    1st vs 2nd design IFS?

    I have really come to find out the turmoil of having a truck from the ******* years Experience and info for 95 down and 98+ are usually solid and available 96 or 97 can be a mix of old, newer and plenty of year specific one off tweaks I have read the service bulletin about the thermal actuator...

    Z71 package differences

    I did not think it was all that much But I certainly have noticed on RockAuto and the like that certain parts will not fit Z71 I almost convinced myself that they came with a proper selectable locker or some type of mini lift for bigger tires

    Z71 package differences

    What exactly did the Z71 get you on the GMT400s? Was is all bolt on extras with a G80 rear end? Did the Suburbans have z71 option then and was it different than the pickup? I know now that a Z71 GM truck seems to be a fancy trim package with strut spacers
