Greasable zirks on chassis

Taking it to my mechanic Thursday and having the front disc brake calipers and pins cleaned and greased, They are squeaking. Replaced the rears recently. I greased the driveshaft myself but understand the Kingpins need greased with the weight off them. I also only found one of three on my  FT chassis grease chart in the steering column linkage. It was in the generator side radiator door. I purchased the springs for the calipers on the soft FT recall to have him add them so they don't drag with heat.
Any suggestions of anything I'm missing on a basic grease job? I did have the differential changed this winter.
Thanks

Do NOT let them grease the brakes with chassis lube.  If either the incorrect grease is used OR the correct bleed process to remove access grease is not followed, you will be spending big bucks.

Also, I would install the brake helper springs while in there.

According to Foretravel Motorhome Lubrication | All Things Foretravel you are not supposed to raise the tires to grease the kingpins.
I just lubed my chassis last week and did not raise the wheels.  Had no problem getting grease in kingpins with wheels down.  If you take it to a shop they usually pull it over a pit to do the service, and they definitely do not raise the wheels.
The older U240 required the front wheels to be raised according to article.

Yes, the "raised to lube" or on the ground depends on the recommendation of your AXLE manufacturer.  Just follow their procedure for your axle.

Well, my little town has no Meritor grease in stock. What can I use besides. I know it's not suppose to have Lithium in it and be high temperature. Goes into the shop in the morning

Greasing brake systems is only required every 100,000 miles. How many miles has the coach been driven since the brakes were last serviced?  If in doubt, leave them alone until you can find an expert who knows how to service them correctly.

On a 1996 they want it much more often. Must be different

Lubing the slide pins will attract dirt.  My understanding is no lube or dry silicone spray if you must.

From the top of page 53 in the Meritor manual;

"Lube brake activating components inside the caliper two to four times during the life of the lining, or every six months "
