Landing gear clunking when down.

We just bought a 38 QB Sanibel. There seems to be a lot of side to side movement from the front jacks. I know I will get some, this is our 4th 5ver. I can actually move the trailer just by rocking it from outside, seems like an excessive amount. There is also a clunking or squeaking noise from the landing gear. I do have the self levelers and I do have blocks under them, as to not use a lot of the extensions.The noise just started this weekend.
Anyone else experiencing this?
Thanks Bob
