Denali Arnotts air compressor/shock write-up (Pictures)

[wade]

****Disclaimer: This write up is heavily rushed as I am trying to get it done ASAP to help you all and I am running late to a lake trip. I had to rush this after work Friday and did not have the time to take more detailed pictures, etc. sorry. This is enough to get you going****

SO don't nit pick me to death







Ok here goes.

My compressor was completely trashed from the elements of nature. shocks blown.

Went to Arnotts and ordered online a new compressor and OEM shocks.

Wiring was a straight swap of wires to attach the new compressor to the existing oem factory harness plug. Just cut the the harness off the old compressor, and match it up to the new compressor. Wire colors ARE the same.

The compressor would NOT just come off the factory bracket due to the rusted seized bolts. So the entire compressor bracket with the compressor attached had to come off at once.

I had to cut the 3 compressor -> bracket mount bolts off and drill them out to allow a 1/4" screw & nut to go through it since the factory stud was immobilized.

Easy over all.
Here is the new arnotts compressor...

Jack truck up so rear axle is OFF the ground.

Take the compressor bracket off via 3 nuts. (2) are visually noticable and one is on the back side of the frame rail. There is an access hole that allows you to have a socket go through it to get the nut off. The studs on my truck did NOT stay in place. They fell back into the frame rail, but there is many little openings in the rail to get a magnet in there and fetch them.

now you see the mounting area with studs back in place...

Here is a pic of the access hole/port on the backside of the frame rail to get the third and last nut off... used a 3" extension

Now onto shock install

Old busted shit...

(DRIVER SIDE SHOCK REMOVAL)::
Here is the TOP bolt/nut. You will need a 21mm open end wrench and a 21mm socket wrench.

Put the 21mm ratchet on the backside of the bolt to hold it steady and from turning while loosening the front 21mm nut with the open end wrench. Its a tight fit for the ratchet but it can be done.

The lower shock bolt&nut come off like pie.

Now to get the bolts out once the nuts are off, you need to get the jack out and place it under the rear axle and slowly jack the rear axle up until it places the old shocks are their natural resting location so the shock isnt pushing/pulling on the bolts NOT allowing them to easily be tapped out.

Use antisieze on all the new hardware and mounting points. Reinstall the opposite way of removal.

NEW driver side shock installed

(PASSENGER SIDE SHOCK REMOVAL)::
This is technically the SAME as driver side shock removal with the exception of the top bolt removal. Their is multiple A/C looking lines that pass all in the area that the 21mm ratchet was placed in to hold the DRIVERS side bolt steady. DON'T panic. All you do this time around is put a 6" or so extension on the 21mm ratchet and go to the bolt from the backside of the frame rail. It will fit tightly though all the lines, etc.. to reach the head of the shock bolt.

Reinstall is the exact same.


Once all is tightened up and truck is back on ground, I started it and heard the compressor come on after a few moments, drove it around, all was well. No more indicator light for the suspension, YAY!

There ya guy Denali guys, my half assed thread for you with CAMERA PICS!


Here is my old DEAD beaten compressor in 2 pieces...

nice post man... gives everyone a nice idea of what is goin on and what we are getting into!!! hows the ride improvement?

 

[wade]

rides way better. the sway is gone.

loaded my 61" **** turf tiger on my 18ft trailer, and when I turned the truck on, the sagging was gone to a minumum compared to before. The compressor was on for a solid 90 seconds and raised the rear up 2".

on the blown suspension, when I towed the mower, my truck sagged like it was towing a ******* dumptruck!

Nice write up/pics. Definitely helpful, and it doesn't look too difficult to do.

In roughly 3 weeks I'll be ordering mine. Gotta wait for the money to come in. I'm going to try the Bilstein replacements, assuming they have some.

Do you live by salt water? Even the frame of your truck is pretty badly corroded. I've been under mine, and it's older and has a lot of miles, but there's hardly any. Just trying to figure out why there is such a huge difference. I don't exactly live in a car friendly place, either. That compressor was just a ball of corroded metal....lol. I'm surprised it lasted as long as it did!!

Thanks for the post. I'll be referring to it later.

 

[Modded]

Nice write up man!!
Your frame si def. rusted out.
Looks like you may live up north or where salt is used on the roads during winter!

 

[wade]

yea, i did not know it was as bad as it was. I bought the truck 2 months ago. It was from cincinnatti ohio

 

[rigo_jones]

damn mine has rust but not that much. it still bothers me.

Do you still live there? If you do I would recommend trying to seal off that compressor better to keep the salt away from it and you might want to look at coating the frame rails so the don't rust any worse.

 

[wade]

i live more south, i already fabbed up a box for it.

whats this coating you speak of?

 

[jomulk56]

You could probably use a spray on bed liner on the box you fabbed up. They also have rubberized coating stuff too. Both of those can be a DIY project.

 

[Fyrcaptain]

shaggy or admin.......

Sticky?

 

[05Yukon]

They sell spray undercoating and bed liner stuff. You could go to your local auto parts store and see what they have. Are those shocks you put on the OEM autoride shocks? I have never seen black ones before.

 

[DenaliAK]

Wade--

How's the ride now?

Couple more weeks and I'll be getting mine done. Hopefully they'll have the Bilstein's in by then.

 

[hoserty]

they make a chemical called POR just Google it not only will it neutralize the rust you have it come in a gloss black that is pretty nice to look at i have used it on quite a few restorations wit 100% success.

 

[DenaliAK]

Just got my Billstein/Arnott shocks and air compressor at the door today. Hopefully I'll get them installed this weekend. Looking forward to (hopefully) an improved ride. I'll let ya'll know.

 

[Tribalbreak]

ahhhhhhhh i guess im the only broke ass dude still saving for my new shit..... sucks saving for a wedding... what am i thinking

 

[DenaliAK]

Took me about 3 months to get enough money to do this, so you aren't alone in your broke-ness. It only gets worse once you're married, too....lol.

But it's worth it.

 

[wade]

DenaliAK, where ya live?

 

[DenaliAK]

Alaska...hence the AK. Anchorage to be more precise. Why?

Got them installed yesterday. Ride is most definitely improved and it just feels different overall. The rear is definitely not as "clunky" as it used to be on sharp bumps. Haven't heard the compressor turn on yet, so it's hard to say if it's working or not, but I'm assuming it is for now. I may have to load a bunch of weight into the back just as an experiment to make sure everything is functional.

 

[wade]

everytime I turn my truck on I hear it run for a brief moment
