Clunking sound is costing me a bundle to fix out of warranty

[demundus]

How can they re-lube both splines from the half shafts in 30 minutes while they charge 2 hours to swap out one driveshaft?

I looked in the service manual and there is no way that it is a 15 minute job to get to the splines out the hub and lubricate them.

What i do see in the manual is that they put greese on the hub, not the splines. Same as what the description of work from mambo says (hub, not splines) Can anyone confirm what they actually are lubricating?

This because I will do it myself and I can make a tutorial (with sound before and after) for anyone here if needed.

Think that just lubricating the half shaft between the hub is doable without removing the whole half shaft. Will definitely try it to get rid of that stupid noise.

I'd be interested in this, i asked my shop to get to the splies to regrease and they got nervous when they were unable to seperate the splines away from the mating face (tesla has a special "tool" for it). If theres an easy to understand way to do this, or go to the next step after what you're suggesting

Check post #8 in this thread... grease at hub, BEHIND the splines:

Rear Axle Clicking

Another data point - had this happen again.. Seems to happen every 115k miles on my car.

Note - it does say 'lubricate at hub'

Great, ordered the following:

* molykote M-77 for greasing
* 2x nut 1020297-00-A
* 2x washer 1020296-00-B

Keep you guys updated in the next few weeks

My 2014 P85+ with 89.8k miles is making the click/pop sound also. I replaced the washers (1020296-00-B) 2@$3.30 and axle nuts (1020297-00-A) 2@$2.20 with new and torqued. Still making the noise. Requested a service appointment and attached a couple of the screen shots of Tesla invoices people have posted in this thread, explaining I wanted the same service these other 2 incidents had (lube & torque). Got a call that a diagnostic was required before service. Tesla offered to have Mobile Service come out. Service came out, we took a brief ride, heard the sound, and agreed the next step is the half shaft splines re-lube at the hub and torque everything down. My service appointment is Oct 8th, so will know more then. I was also told the charge for the required diagnostic ($97.50) would be applied to the service visit. The estimate PDF I was sent shows the labor charge to be $97.50. Also noticed the Service Center hourly rate is now USD $195.

Handy tip another Mobile Service guy showed me... using a suction cup the size of the center cap on the wheel will pull that cap right off. Then you can torque the axle nuts w/o taking the wheel off. There were no cotter/split pins on the axle nuts to deal with either.

Had the service done today, happy to report the noise appears to be gone. The diagnostic fee was applied to the work, making it a $97.50 job (plus my previous washers/nuts purchase). If I have as good of luck as @gaswalla and only need this service every 90k miles or so... I'll be satisfied as well.

Almost there, only thing that's missing now is some spare time...

Interesting note - tesla tech says that they can measure the slop in the splines using the indicators on the brake system. In my case they ruled out the splines by doing this diagnostic - and want to replace four linkages and the integral arm.
