Installing the One Ton Front End Version II

Before you start, order these parts:

You'll need right and left front brake calipers for a 1996 GMC/Chevy Suburban Diesel 4x4 with 8600 lbs GVW (also referenced in parts catalogs as having 13" rear brake drums). Order "loaded" or "semi-loaded" calipers so you get all the hardware required. If you get "semi-loaded" calipers, you'll also have to order brake pads.

Note: These are NOT the same calipers as the 80mm upgrade to the OEM front brakes.

Some sample part numbers are listed below. Unless otherwise noted, these are loaded calipers (include pads):

Bendix L55496M & L55497M
Centric (semi-loaded) 14166019 & 14166020, Ceramic Pads: 30103700 (Note: The Centric calipers I got rubbed on the inside of the Alcoa wheels. I had to grind a little off the rough casting of the caliper body to clear the wheels.)
Raybestos RC11985 & RC11986
Wagner Quick Stop L116294 & L116295
Wagner Sever Duty S116294 & S116295

If you haven't already upgraded these parts, you should also consider getting:

Sway bar end links: Moog K446 (need two kits)
Sway bar frame bushings: Moog K5253
Tie rods (need 2 of each part):
- Inner end: Moog ES361R
- Outer end: Moog ES412RL
- Center tube: Moog ES2004S
Shock absorbers (There are a number of choices. Here are two common ones):
- KYB KG-5435
- Bilstein 8460940

If you find the upper A-arm cam bolts are stripped, order Moog K5266. Specialty Products Company (SPC) 83160 will also work, but the cams are slightly smaller. One kit does both sides of one A-arm, so to replace all you'll need two kits.

The seals on the back of the knuckles have been inspected and determined to be in good condition. There are also dust shields on the new axles that fit over the seals for extra protection. If you prefer to replace the knuckle seals with new ones, the NAPA part number is NOS 31504.
