How to change rear shocks on Tesla Model Y 

Did the new shocks made a big difference on the ride quality? Thanks

I see most people are cutting the stock bump stock, has it been a problem keeping the whole thing instead of cutting it?

Do you have a rear shock absorber making noises, do I have such a problem?

I recently did the same install, sucks that the dust boot bottom mount can't be transferred over, though zip ties seem to work. Is there a reason why you reused the nyloc from the OEM shocks instead of the metal lock nut? Also Tein specs the torque for their lock nut to be 25Nm, would it be bad to just use use the impact drill to secure it?
