Question about 1999 Cadillac DeVille
I bought a beautiful 99 DeVille Concours last year, casual sale. Have a young mechanic friend who keeps it together for me. Have had to do some minor repairs but, over all it's a great car. Only problem is a nagging noise that sounds almost like the jack and tire iron are rattling in the trunk (noise comes from Passenger side rear suspension area. Noise starts when you hit road speed and any bump will get it rattling. Goes away (temporarily) when you apply the brakes.
My mechanic buddy is rarely stumped (keeps older Caddies running for his dad and uncle as well as me) but this one is killing both of us. Everything in the suspension area is tight, even the knuckle bushing that goes on all old Caddies after 100K miles or so). Shocks seem solid - don't want to tear out the suspension to replace them if it's not necessary.
any one else had this problem? any suggestions? Hate to spend the big bucks to have a dealer tell me it's a loose nut (besides the one behind the wheel).
The rattle is probably not coming from the back. I had a similar problem with my 1994 Deville. I took out the jack and spare tire. I replaced the front anti-sway bar links (my mechanic said the ball joints were rusted on the links). Nothing worked. The solution was to replace the rubber bushings holding the front anti-sway bar to the frame. These bushings disintegrate and theanti-sway bar clicks against the frame. They are out of the way and so don't get noticed.
