I did not see a grease zerk on mine but normally it will release when there is no load on the wheels. Same as when you shift out of four wheel drive when turning on your 4X4 and it won't actually release until you straighten the wheels and take off the load on the gears. Or so it seems to me. My L4350 acts the same way.
All the telescoping arms do is make it a little easier for you to hook up you 3PH implements. They may be a bit heavier built but not sure on that.

I had telescopic arms on my L3240HST but don't on the tractors I have now. They actually make it alot easier to hook up implements. I have quick hitches now. To me telescopic arms aren't worth the price to add them but they are nice.

I agree with John, they make it a LOT easier. I went from telescoping arms to non-telescoping. I still kick myself. Bought a Pat's system to help with the hitching problem.
You can buy lower arms for the B2910 or B3030 for somewhere around $350. Neil Messick could tell you closer. They'll fit your B7800.
The B2910/B3030 with telescoping arms and position control is a whole step above the B7800 for 3pt tasks and worth every penny if used a lot.
the thing that got me thinking about the tele arms is this. In the past when I have finished sheet rock the angle of the blade on the mud is crucial. I thought with the tele arms I could get more of a desired angle on a rear blade for feathering dirt,crusher run or snow??? Also looking at Messicks site they show the tele arms with a bracket which the parts man says is needed? why can't you just get the arms and connect them to the existing apparatus on the B7800 .
What is the difference between the inching device on the B7800 vs the position control on the B2910/B3030

Your toplink will adjust the angle of your blade, the futher its turned out the more agressive your blade will be. The tele arms are just for easyer hook ups,as John Thomas said.
Position cotrol gives you more precise cotrol of your rear implement. for a detailed explenation do a search there have been some good post on the subject.

As others stated. The tele arms just slide back and forth for hooking up an implement and don't change any angle, just slide back and forth. Position control lets you visually see a position beside the 3ph lever, usually a number, and then you set the lever at that number the 3ph will always drop to a/the specific point on it's decending travel unless something stops it. 3ph's lift with power and drop till they stop, either at the bottom of their travel or until some resistance that is stronger than the weight going down makes them stop which means they float when lowered. Incremental controls drop a certain distance or steps(!/4" !/2" 1") each time you push the lever unless you push it all the way which is supposed to drop it all the way to bottom or until resistance stops it. My B7800 had incremental drops but my B3200 just drops till I let go of lever, then it stops so it has no steps.

if interested in the Telescopic Stabilizer Kit, you do need the whole kit for the arms to connect correctly i as others have gotten the kit at tractorsmart.com, under $200 including shiping when i ordered less than six months ago

We're getting a lot of confusion going here. I don't believe the OP is talking about the stabilizers, I believe he's talking about the 3pt lower arms that telescope.
The telescoping arms will not assist you in setting the cutting angle or pitch of your blade. They are not designed to be used in the unlocked position. They are used to assist in attaching equipment. Back up to the attachment and stop with the arms just a couple inches from the pins. Unlock the telscoping arms, unpin the stabilizers and hook the arms to the attachment. Repin the stabilizers and connect the toplink. Get on the tractor and gently backup until the lower arms reset themselves and lock. No dragging the attachment around or prying on the arms to get them hooked. No comparison in ease of use between telescoping and non telescoping.
The top link will only assist you in adjusting the pitch of the blade. It also will not have enough variation to help with aggressiveness of the cut. It is more likely used to give you a variation in height that you can lift the moldboard. If working on flat ground you want the frame of the blade to be level when the cutting edge is sitting on the ground. This keeps the moldboard flat when the angle of the table is changed. If the frame is not sitting flat and you angle the molbboard one end or the other will elevate depending on how unlevel the frame is. When shaping a drive you should set up the blade with the table/frame sitting flat by lengthening/shortening the top link.
The right side adjusting link on the right side lower arm will give you some cutting angle adjustment. This is used to cut a certain grade in relation to the tractors position. Good to "crown" a roadbed or dig a drainage ditch. I normally want the right side slightly lower than the left when crowning with the table/moldboard turned with the right end of the moldboard ahead of the left side and the tractor being driven on the right side of the roadbed. It's just more natural for me that way. It results in the loose material being dragged to the center of the roadbed.
The aggressiveness of your blade is going to have to be controlled by the 3pt lift. That's where position control comes into play. The height of the 3pt attachment can be infinitely adjusted with position control 3pt. In the case of the B7800 the adjustment is jerky and seems to have a mind of it's own. It can be learned by the operator and satisfactory work can be done. But the position control system makes this learning curve a lot smoother. Also if trying to fill a low spot the 3pt attachment can smoothly be lifted as the tractor moves forward to dump materials where needed without humps/speed bumps.
Practice, practice, practice....
