2014 Gen1 with 30K miles clicking axle accel/deccel problem. I re-torqued 3 months ago, silenced the problem but got the updated parts anyhow. I just did the nut/washer update on one side yesterday.

The topmost hub bolt is a PITA to get to. It helps to turn the steering wheel to allow access (NOTE! you do not need to turn on the car to do this and doing so will likely expand your brake caliper piston, making it impossible to put back over the rotor).

Only a few tools are required, 3/8" ratchet with 10mm (hub wheel speed sensor) and T30 (rotor retention) and medium extension. 1/2" ratchet with 21mm (caliper bracket bolts), 18mm (hub retention bolts) and various extensions. A wobble extension could have helped, perhaps. Bungee cords to hold up caliper while it is off. And of course 32 and 36mm axle nut sockets and a torque wrench capable of 185 ft-lbs of torque. To do it right you also need a smaller torque wrench to get the caliper bracket and hub bolts correct.

I may just leave the other one stock and compare the "permanent fix" to "just re-torque when you hear clicking" methodologies.

Anyhow, here is a picture of old (top) and new (bottom) hardware. The old, broken washer fell out as I pulled the hub assembly away from the axle.

Great info. I'm trying to decide if it's worth the trouble. Do you think it would cause damage just to let the hub click without replacing the washers?

Yeah it is great info and how did I miss this back in 2018 when it was posted?

On my ELR, I had a click on one side only. Dealer refused to tear it apart to do the washers, but did install the new larger nuts, and torqued correctly. One year later, still no click. If it comes back I will take it apart myself and do it properly.

That's good Jay, the dealer tried the same thing with my car. When it started clicking again 6 months later, I ripped it apart myself and fixed it right. Been about 18 months since I fixed it and still no noise.

Figure I should be good until I get rid of the car....

I'm wondering if it's the broken washer that's causing the clicking sound?

That was my immediate thought as well. One sure way to tell is to take a drive up north to Sly Bob's place and have him show you how to fix it right. ;)
