Drive Shaft Grease Nipples

I saw another post on this subject but could not reply back so have started a new thread.
I phoned the dealer that serviced my new to me purchase last week (2008 Dutchstar) and they say there are no more grease points on the driveshaft. I am not sure if this is correct! Does anyone out there know any different? My shaft is the original one and if it needs grease before we head to Tucson then I want to do it. I will climb under on Monday on a creeper and take a look even though it is cold out. Is there a diagram of grease points for this vintage coach? I might also phone Spartan on Monday as this is important to me.

I would be crawling under there with a fully loaded grease gun, if I were you.

Sounds like this guy just left a car service center

My 2008 DSDP has all the usual grease zerks on the drive shaft. Best I can remember without being under the mh there two on each u-joint and one on the sliding spline seal. It helps access to have the air bags aired up and shaft as straight as possible when lubing. The only person I trust to get all the lube points is me, even though I hate lubing.

There are 3 zerks that need to be greased. Each u-joint has 2 but you only need to get the one that is easy to get and keep putting grease in till the grease comes out all 4 caps.
Do each u-joint and then the sliding spline needs to be greased till grease comes out the end. We were at Spartan last summer and a owner was there with his Essex and needed 1700$ worth of drive line work because the drive line was dry and damaged drive line. He showed us that he had had the coach grease but they just didn't do the drive line. Is tight and hard to do but very important.

Good advice, Attached is a Spartan drawing of your driveshaft. when you apply grease to the u joints be cautious not to overgrease them and push the seals out. I grease mine about every 5-8K miles.

As stated, two fittings on u joint and one on spline. When you grease the spline, there is a hole on the end, between the end of the spline and u joints. Once the spine is full, grease will run out of that hole. Take you finger and plug the hole until grease starts running out of the slip joint at the other end.

Because of the torque these drive shafts see, it has been recommended that they be lubed every 5K.

Lastly, here is a great grease gun tip that locks on and make it much easier to grease hard to reach fittings.

What ever you do be shure you get grease out of EVERY cap. I grease till I get clean new grease out and wipe off the excess. If you don't get grease out of every cap it is recomended you take the drive shaft out and disacemble it and find out why.

Both our DSDP's and now the Magna have zerks on the u-joints and the drive line slip joint.

So turns out the Newmar dealer principle was full of It and did not know what he was talking about. Service guy had greased everything and I mean everything. There is new grease on all the u-joints and slip joint as well as slack adjuster and steering and suspension. All good for Tucson trip next Monday

People like this drive me nuts. We are in the process of buying a new mattress for the SB. People selling a product they have No Clue about. Agh..

I have a 2015 London Aire and I can't find the grease fitting on the slip joint. There looks like a sealed unit. There're two grease fittings on each ujoint but not on the slip joint. Anyone knows what the reason and am I missing anything. My other two mh had the fitting and greases while holding the hole till grease came out the spline.
Steve Mosher. It was recommended every 5,000. Miles

I am shooting in the dark here but some of the more modern diesel pickups have those little flush zerks in the driveshafts and some times they are difficult to get to. This might be your case as I find it difficult to believe they would not allow that spline to be greased when it works every time your wheels go over the smallest bump in the road.

I would inspect it with a good bright light. Look for the possibility that they didn't install a fitting or there is a plug to take out and install a fitting. I would call and ask.
