What does a failing catalytic converter sound like?
Rattling Noises. Your catalytic converter consists of small, honeycomb-shaped components that can cause a rattling sound when broken. If your catalytic converter is broken, this rattling should be loudest when the car starts, and should get worse over time.
What are the signs of a bad strut?
The Warning Signs Of Worn Shocks And Struts Instability at highway speeds. Vehicle “tips” to one side in turns. The front end dives more than expected during hard braking. Rear-end squat during acceleration. Tires bouncing excessively. Unusual tire wear. Leaking fluid on the exterior of shocks or struts.
What does it cost to replace struts?
To replace a pair of struts, the total cost on average is between $400 and $1000, including wheel alignment. An individual strut assembly costs approximately $150 to $350, while the labor cost is $100 to $300 for a pair.
How much does it cost to replace strut mounts?
Replacing a strut mount will cost you somewhere in the range of $120 to $250 total (parts & labor). The strut mount itself will only cost around $40 to $100 in parts.
What does a rattling catalytic converter mean?
Rattling Noise – Once your catalytic converter becomes older or damaged from fuel mixtures, the honeycombs on the inside can begin to collapse and/or break apart which will cause a rattle to occur. This misfiring can cause the catalytic converter to overheat as well.

What happens if you don’t replace struts?
Safety: Worn struts result in longer stopping times and/or distances as the vehicle weight can shift (sometimes unexpectedly) during braking. Wear on other parts: Driving with bad struts accelerates the wear on tires, as well as other components of the suspension system, such as the springs.
Are struts worth replacing?
Struts don’t need to be replaced unless your vehicle is bouncing like it’s on a pogo stick or bottoms out in potholes and over railroad tracks — or unless a mechanic finds that they’re leaking fluid or have been damaged. The struts limit the resulting bouncing caused by the springs compressing and releasing.
