Stop in for a cup of coffee

Still cold here again. This -20 **** needs to go away.
Busy day today i think.
Quick service before guy goes to work. Toyota for a pinion seal.
Chevy pickup making horrible noises in 4wd, sound like a pinion bearing or something. A dry grinding noise. Weird...

Does the Toyota have a squash collar? I'm having flashbacks of "use the right amount of torque" at first, then having to break out the inch pound torque wrench to set preload.....or something like that. 86 4x4 pickup.
