Front pinion help!
Im in the process of putting a new pinion seal in the front of my 2000, when I took it all apart, I noticed that there is no washer underneath the nut that hold on my yoke. My question is should I just put it back together the way it was, or should I put some type of washer in there?

Pinion Gear
1) Install oil slinger (front axle). Press rear bearing on
pinion gear shaft. Place original shim (or see ADJUSTMENTS) in rear
bearing bore, and install rear bearing race.
NOTE: Install shim so chamfered side is toward bottom of rear
bearing bore.
2) On all axles, install front bearing race into housing.
Install pinion gear. Install front bearing over pinion gear. Apply oil
to seal. Install seal, yoke, washer and original pinion nut. Tighten
nut to remove bearing end play only.
3) Remove original pinion nut, washer, yoke and front
bearing. Install NEW collapsible spacer on pinion. Reinstall
components and front oil slinger (if equipped) in order using NEW
pinion nut.
4) Preload pinion bearing. See PINION SEAL & YOKE under
REMOVAL & INSTALLATION. Using an INCH-lb. torque wrench, check pinion
bearing preload by measuring torque needed to rotate pinion gear. See
PINION BEARING PRELOAD SPECIFICATIONS table. If preload is not within
specification, see PINION BEARING PRELOAD under ADJUSTMENTS.

Seems according to this service manual you should have a washer, but I've seen some cases where you don't have one. You did get a new nut right?
