I was told my car needs motor mounts, it cluncks quite a bit when i hit bumps, the bigger the bump, the worse the clunk. How important is it that i get it fixed? I think i have been driving with it like that for a while, i say i think because there are other issues that are particularly noisy, that i just got fixed, so now i can hear
Sounds more like struts/strut mounts and sway bar links and or other suspension stuff…
Engine mount clucks is more when putting it in gear and or when you hit the gas pedal…
Engine/trans mounts are important, they keep the engine from falling out of the car… lol… The engine/trans moving around will stress the axles and cause early failure, it can/will cause wiring harnesses to stretch, hoses to stretch…
I have had all my shocks and struts replaced as well as the sway bar
I was told it was the motor mount
Presuming your shop are experienced pros, suggest to trust them. Your Sentra is nearly 15 years old & could very well need the motor mounts replaced. You could ask your shop to show you the test for why they think so. A common diagnostic is to start & idle the engine, then a helper steps on the brakes (to prevent car from moving) while shifting from R to D several times. The mechanic watches the engine compartment from the front & notes how much the engine & trans rotate. As mentioned above, you’ll be money ahead to replace them now rather than waiting, presuming the testing shows that’s needed. I should mention that my 30 & 50 year old vehicle both have their original mounts, so they can last a long time. The 50 year old is scheduled for new mounts next summer.
