* Suspension Components: This is the most common cause. Look for:
* Worn bushings: Rubber bushings in the suspension control arms, sway bar links, and shocks/struts can dry out and crack, causing squeaking, especially during turns or over bumps.
* Worn shocks/struts: While usually associated with bouncing, worn shocks/struts can contribute to squeaking, particularly if the internal components are rubbing.
* Leaf springs (if applicable): While less likely on a LeBaron convertible, if it uses leaf springs (though more likely to be coil springs), dry or rusted areas can squeak.
* Loose suspension bolts: Check all bolts connecting suspension components; loose ones can cause metal-on-metal squeaking.
* Brake System:
* Brake pad wear indicators: These small metal tabs on brake pads squeak when worn to warn you that the pads need replacing.
* Brake caliper issues: A sticking or seizing caliper can cause noise.
* Body/Chassis:
* Loose body panels: The convertible top mechanism or related panels might be rubbing against the chassis, especially if the top isn't properly latched or adjusted.
* Rust: Rust in the chassis or suspension components can cause squeaking as metal parts rub against each other.
* Exhaust System:
* Loose hangers: The exhaust system can rattle or squeak if the hangers are loose or damaged.
Troubleshooting Steps:
1. Reproduce the squeak: Drive the car and try to pinpoint when and where the squeak occurs (turning, braking, going over bumps, etc.). This will help narrow down the possibilities.
2. Visual Inspection: Carefully inspect the rear suspension, brake system, exhaust system, and body panels for any obvious signs of wear, damage, loose parts, or rust. Jack up the car safely (using jack stands!) to get a better look at the underside.
3. Lubrication: If you suspect worn bushings, carefully apply a silicone-based lubricant (NOT WD-40, as it's a temporary fix) to the suspect bushings. This is a temporary fix to see if the squeak goes away; if it does, bushing replacement is needed.
4. Test Drive: After lubrication or any repairs, test drive the car to see if the squeak is gone.
If you're not comfortable working on the car yourself, it's best to take it to a mechanic for diagnosis and repair. Describing the squeak (high-pitched, low-pitched, constant, intermittent, etc.) will help them diagnose the problem more quickly.
