suspension squeaks when weather is dry

this just started happening last month. my suspension or steering ( dunno which is problem) in the front drivers side squeaks when i hit a bump or a turn. this doesnt happen in the rain! is this a problem compounded with a leak in my shocks or is this just a plain dry-up steering bushing? i think my front passenger side shock is leaking. the car sinks after i parked for an hr. problem #2, i caught a flat tire in my back passenger side. droved it for a little bit to get off hwy. maybe i didnt press a button before i jacked it up, now when i hit any big bump my back wiggles out( as in no traction sliding sideways). is that a alignment problem or driveshaft, tsc dead?

the squeak is your control arm bushings and ball joints , sound like a old carriage ride . They don’t have lubrication fittings so some people inject them with a grease gun needle but the right way is to replace them

the loss of traction/fishtailing is an unrelated issue . The damaged tire tread may have hit a suspension wire connector

there are airmatic /abc/abs /wheel speed sensors all in that area , unknown what could have been damaged . Get it inspected by a good Mercedes mechanic paying particular attention to the area of the damaged wheel

S550
I have a 2015 S550 with the MBC Suspension option. Just recently, the front suspension has been squeaking when met with minor imperfections in the road. I'm concerned as to why this is occurring since it has a mere 36,000 miles on the car. Any suggestions?

it’s the same issue , Mercedes ball joints and control arms does not have grease fittings to lube the joints
