CAr shake

2fast2lexury · May 5, 2018

Hey , i'm bew to these forums but i was wondering if someone could answer this. My lexus was once quiet as a mouse, now its loud as if there's a hole in the exhaust somewhere . However , sometimes the car shakes in a back and forth motion while driving, ive changed the spark plugs and coils was fine , i was wondering should i get a whole new exhaust or is it my catalytic converter all stopped up , or flex pipe needing replacing ?.

2fast2lexury,

First off, always give us your mileage as it narrows down what your issue might be. We also need the year and model, but your signature gives us that info.

Don't buy anything ... until you know for sure what you actually need to fix the problem. Too many people throw parts and money at a car to fix a problem only to find out later that they didn't need to replace that part, because something else was the culprit.

Your question says that you know very little about cars and repairs, and that's alright. So you need to get your car to a good independent mechanic who can put your car on a hoist and find your exhaust leak and tell you exactly what needs fixing. It may be as simple as a broken exhaust flange that needs rewelding, or you may need a new muffler, or the exhaust manifold may need a new gasket.

The same for your car shake. Go with the mechanic on a test drive and have him diagnose what the problem is. It could be a flat spotted tire, a leaking strut or as simple as as a lost wheel weight. If you don't know ... then you need to find that trustworthy independent mechanic. Don't go to a Lexus dealer .. unless your car is under warranty (your obviously at 21 years old isn't). Your car is just a gussied up Toyota Camry, and any good service tech can fix it for a lot less than Lexus will charge you.

Ask your friends or relatives to see who they recommend for car repairs. The independent mechanics will always be cheaper than a dealership, because they don't have those huge parking lots and fancy buildings to pay for and keep up. Good Luck!
