Full Lock's 2004 Avalanche Z71 (beater)

[Full Lock]

GM auto trac II for the t-case

GM Dex VI for the trans

 

 

Mobil One 80/90 synthetic for the diff (got a 15gal drum of that at the shop)

And DOT4 for the brake fluid

Are you 2wd? Thought the rear diff used 75-90 or something. 80/90 for the front sounds right.

 

I figured I would wanna go after GM fluid for the transfer case. Had to do that with my 09 Ram that had an auto select transfer case. It was very picky on the fluid.

No im 4wd it's what I've been using for the past 15 years and never had an issue with the slightly thicker diff fluid

Yea the worst it would do is lower your fuel mileage a little.

I went down to the shop just to drop my lines off, they were dead so I had a lift all to myself. Every step faught me the whole way. From the spare tire hoist (going To be replaced), to the broken weld on the nut that holds the bolt for the rear gas tank strap, to the rear caliper bleeder that was frozen (replaced the right rear caliper). I couldn't install the SS braided hoses cause the left front hardline was twisting as I was trying to remove it.

it was such a tough day. I was too busy today dealing with issues to take more than a few pics. Going back tomorrow and I have the help from my buddy that was a GM tech and another that has done 10 of these installs, so hopefully it should go smoother than today.... don't see how it can't haha.

 

This is what the lines look like at the brake module.

 

What the line looked like when it was finally out of the truck.

 

Where it broke, it didn't make it out in one piece

 

First New line in

 

 

The truck is drivable now but all the other lines look just as bad as the one that I replaced today so it's really not safe to drive. I got lucky how the incedent went down last week (that's how I'm looking at it don't want it to happen again and may next time it could be at 70-80mph instead of just 35-40). I will hopefully finish up the last 4 front lines and install the SS braided hoses as well. I'll try to get some more pics of the process tomorrow.

Dealing with those lines is not fun at all. I've replaced a few of mine, but not all of them. I had to replace the one front line when I installed my braided lines because it did what yours did which was twist.

[Full Lock]

^^^^right after spraying it down with some freeze off it came off yesterday day but it needed to be replaced anyway. The right front was the most challenging because of the way it's routed. After them getting that line in the rest were fairly simple.

Replaced the rest of the lines yesterday. It only took hour & half to get the lines in place.

 

 

 

 

Then after just afew hiccups we installed the SS Braided lines

 

 

Moved on to the rear but had a small issue. So I just reused the banjo bolts that came out of the calipers

 

 

 

 

 

Compared to Friday, yesterday was a breeze. The truck now has a very sturdy pedal from the SS braided line upgrade & a properly bled system. (Right rear caliper couldn't be bled previous because of the frozen bleeder) and has all new fluid so I couldn't be happier.

[Daryl LBZ]

Braided lines are nice, my trucks pedal is definitely firmer after I installed mine.

[Full Lock]

^^^ right I've had them in most of my past cars but first time on any of my trucks. Now everything I drive will have SS lines.

next im goin to talk to a buddy about helping me replace my rockers.

[GrumpyGhost]

Nice truck! I'm replacing my rockers right now myself, check out my build over the next week as I'm doing them. They are a real pain. If you have the ability to do them yourself, you'll save quite a bit of money as I was quoted $1400 just for the rockers.

 

I also just replaced some brake lines on my truck and I feel your pain of the broken and rusted bolts/nuts.

I got a quote from a buddy thats a painter for a body shop and with me getting the parts, it was $1000 in labor.

So I have another friend that's a body man and has a shop at his house that said he would help out. so hopefully I'll be getting that done in the next few weeks when our schedules line up.

Damn rust is killin me on this truck.

 

 

WORKING ON GETTING MY PICS BACK UP

[Full Lock]
