Grease Fittings

I would google lube charts for the chassis you have and I bet you will find them. My 2005 owners manual tells me where all of them are. My 97 Imperial manual looked like it was written by a 10 year old....

Cvettester.....Let's start at the front. Your steering column should have three fittings. One is visible from underneath, one is half way up the steering column shaft and can usually be accessed with the generator slid out. The third one is under the cover of your steering column, inside the coach.

The front end has it on both the top and bottom of the kingpins. All of the steering links and the brake assembly (cans/slack adjusters).

The drive shaft has two on each u-joint and as mentioned, you only need to get to one to fill the entire u-joint. The slip joint on the driveshaft has an obvious fitting, but you have to find the relief hole at the end of the slip joint, between the slip joint and u-joint. Usually, you can reach your middle finger in there and cover the relief opening while you pump grease into the slip joint until it oozes out of the end of the slip joint (spline end).

The rear end has it at various joints that will be obvious and also at the brake cans and slack adjusters.

15000 miles is the standard service interval with the driveshaft requiring lubrication every 5000 miles per Monaco.

I have a 2001 Imperial and it has zerks on the driveline,brake cams, slack adjusters,front steering components,steering column. When greasing u joints I usually stop as soon as grease appears to squeeze out of the caps. Too much can damage the seals and they wont retain the grease as long.

RE: drive shaft zirks on a DP:

Counting the two U joints, there will be 5 zirks-- as most U joints on DP's have two (180 degrees from each other). You only have to grease one of the two, as they go into the same area in the center of the U joint. The other one is the one of the slip joint.

Bret,
As a follow up on the U joints, make sure you see grease come out from all four bearing cups. If not, switch to the other zerk and/or relieve the tension on the u-joint by rotating the drive shaft or by prying slightly on the joint. Sometimes pressure on the joint will keep the grease out.

Also, on the slip joint you may need to hold your finger over the small pressure relief hole to get grease all the way to the splines.

I read about another trick to keep the shaft/u-joints from slinging grease all over the undercarriage. When finished greasing the joint, wrap some saran wrap around the shaft/joint area to catch the grease when it first starts slinging. You can then remove the wrap. I have never tried that as I don't like the idea of saran wrap being slung around but I guess it would work. I think most of the time we probably use too much grease and just sling it around but I want to see the grease myself.

22 grease zerks on my '95 Gillig chassis.

Don't be surprised if you don't find any. Most bearings are sealed and do not require greasing like old ones did.

Actually, on a DP, most WILL have zirks and need to be greased. I am betting on 10+ zirks.

Yep, I counted 13 on mine the last time I greased it. There's also one on the drive shaft.

What chassis is it on?

Good luck finding information about lubrication points in the HR owners manual. The owners manual for my 1994 HR Vacationer is the most pathetic excuse for an owners manual I've ever seen in print. Their answer to EVERYTHING is take it back to the dealer.
