F53 popping front end noise
My 2007 22K chassis w/105,000 miles did this, and now my 2017 24K chassis with 20,000 miles. Both Fleetwood Bounders... 33R, now a 36Y
When turning the steering wheel either direction, going over dips, or steering left-right-left-right making the RV rock and roll, I get a popping (binding?) sound from the front right corner. Every time.
On my 2007, I checked and greased the kingpins as well as all joints, had front off ground and checked for binding, (I could turn the steering by hand at the wheels smoothly) and also had replaced the OEM rubber SB bushing with urethane ones and lubed during the install. New Koni shocks. All with no change. I just bought the 2017 last week and its still all stock, haven't had any time to look into it in depth. On the 2007, it appeared to lessen after it was driven for long periods, (all day), but once parked for a few days, back to square one. I have only driven the 2017 1 hr from place of purchase, so no baseline. Just that when I move it in my driveway, it pops!
With both RV's doing the exact same, I am thinking its a suspension noise, that may be common among the F53 chassis. Any ideas?
