Relax, I used your post to prove a point. There is a poster who suggests everybody ignore what can be learned on internet forums and just "trust" his trained mechanics.

I used your post to make a point. We KNOW that driveshaft splines fail. We have pictures from our members that prove it. The Suzuki service manual recommends lubrication on assembly but no where else is it part of periodic maintenance. We have numerous reports of a lack of lubrication, AND many of these reports are on both older and newer bikes. It doesn't take a rocket scientist to figure out that the lack of lubrication is coming from factory assembly seeing as that is the LAST TIME the driveshaft/coupler had been apart.

How can one just trust a trained mechanic when NONE of that mechanic's training tells him to lube those splines as a part of routine maintenance ?

No where does Suzuki say to lube those splines OTHER than on assembly.

My point is dealers don't have all the answers and I just quoted you to make that point but I wasn't necessarily pointing any fingers at you.

If you would maintain your bike on its schedule, or have a qualified shop maintain it...it would never be a problem.
Because nowhere on Suzuki's schedule of maintenance procedures does it tell a "factory trained mechanic" to remove the driveshaft and lubricate the final drive end of the splines as part of scheduled maintenance.

But if that same mechanic had ever logged on to VolusiaRiders.com he'd know just how necessary it is.

Just trust your factory trained mechanic. He's been trained to tell you...

1) "yes, they all do that"

2) "it must have been something you did"

When I installed my DJ drive, I found what most others did - the drive shaft splines were bone dry, no grease at all.

I do most of my own work - learing what I need from the experts here on the site. The few times I have taken my bike to a 'factory trained tech' the bike has come back missing parts or with damage and I've had to take it back and force them to make it right (I'm talking about the Suzuki dealer where I bought the bike). There are plenty of great shops out there but the key is finding one. That said, any mechanic who treats me with contempt when I ask a question or snorts at the idea of customising a bike is one that I would never use.
Does the book tell you when to fill up with gasoline? No, because it's common sense that you do that when or before you run out of gas. It would stand to reason that a splined shaft needs periodic maintenance. I know from the Nomad forum that Kawasaki is very stingy with the lube on their gear drives as Suzuki apparently is.

I do all my own work as well, I haven't yet met a technician I trust as much as I trust my own abilities. I'm not saying there aren't any, just that I've yet to find one. That includes Harley techs, so you know I am not biased.

Actually it does - even shows where the gas cap is and what octane to use and also warns about ethanol. They even give this cool thing called a gas gauge so I know when to fill up.

I just don't see how a little grease normally placed on the splines to make assembly easier to accomplish is going to keep splines from failing.

The proof would be in how many splines failed when grease was applied.

It's a good plan to grease the splines but I doubt if it's a magic bullet that will prevent spline failure.

Actually, two red, that little bit of spline grease, along with checking rubber boots and exact fluid levels in the final drive will result in a final drive that should last darn near forever. I have a lot of experience with shaft drive bikes with well over 100000 miles (i've owned 3 bikes that clocked over 100000 in my care, two of them are still on the road and one is permanently attached to a toyota

If its lubed, and it is aligned properly and doesnt come apart early, there is a chance it should literally last longer than any moving part on the bike. You are correct in assuming the vol is a value machine, but shaft drives last forever and a day.

My last old school beemer was pulling a sidecar. I decided to completely strip the final drive to look for signs of excessive gear wear. My tech, the best in the US, looked at me like i was crazy and told me that if it wasnt broken at 75k, it would probably last indefinitely.

So, you can see why us shaft drive fans are so anal about using a great moly paste lube and ensuring we generously and properly grease the splines. Done so, just a few times in a lifetime, will keep the part working indefinitely.

On my paris dakar, the driveshaft was pulled and lubed at 40,000 miles, then not touched again until 150000 miles, then never again. You can see how just making sure the grease is done it will work a long time.

Take a look at the pics of failed drive shaft splines in this thread and tell me that a bit of moly paste would not have been a good preventative maintenance measure.

Again, I'm far from a mechanic, but I have to say that I've never heard of anyone who greased their shaft having a failure. I don't know, maybe it has more to do with the owner giving some attention to the shaft than the actual grease, but it's enough to make me believe it's worth greasing it.
