2014 RSS squeaking sound over bumps...annoying!!!

[On1wheel]

Has been happening for the last 6 months. Took it to the dealer, who said it was the sway bar bracket...an elongated bore hole for a fastener. Should have been a warranty job, but didn't have the stock parts, so I sprung for the Baja Ron sway bar kit & accessories, which I was going to do anyway. They also found two other suspension parts that were faulty & replaced those too. $1000.00 in parts & labour & it still squeaks when the rear wheel goes over a bump...like a 1950's pick-up. I'm beyond annoyed.
Anyone else have this or even has another idea as to what it is?

If you're sure it's coming from the rear it could be the nylon shock bushing or the swing arm bushings or bearings. If you are handy you could raise the rear wheel and unbolt the shock and test both the shock and swing arm.

Check the rear shock bushings. Jack up bike, remove lower shock bolt. Move swingarm up and down. If no squeak, clean and replace bolt. Move swingarm up and down. Have good ears!
