So my 03 S430 started creaking from the rear drivers side this winter. Started when it was -20 out, and went away after it got above 0 so I chalked it up to cold weather. Well it's 50 out now and it's starting to creak again so scratch that diagnosis.
Any thoughts what I might be in for? I've sprayed some lube on everything I can see as far as joints and bits. I can't put my finger on exactly what is making the noise. Sounds like it's more in the suspension and not the airmatic. I'm thinking a dried out bushing. I'm not experiencing any clicking, so not a shot ball joint or tie rod.
Anyone have any ideas? I'm sure a visit to the dealership is in order, but I thought if anyone had a magic spot to lube I would try that before parting with my hard earned cash.
Thanks

Any further conclusions or was the problem solved? I have bad squeeking in rear suspension, both sides. Tried lubricating all bushings but to no avail.

Ended up being two worn bushings. The fix cost me about $500 if I remember correctly.

Mine's being done tomorrow, both bushings drivers side. I ley you know the cost later.
