Help! My car likes to rumble/shake when at approximatly 55-70mph... Then its stops after I go faster or slower... What could it be?

 

Everyone says its alignment. I think. Also your tires could be going bald, I know I had a bald spot on mine from some excessive braking incidents and getting new tires helped.

 

get your wheels balanced.

Bingo. If the shop says they're balanced, go somewhere else. I believe dealerships balance them on the car.

 

What kind of motor and/or mods do you have? A aftermarket clutch or lightened flywheel, maybe?

 

I don't think it's your wheel balance, but you can test it by rotating the rear tires to the front and see if the problem goes away.

If that doesn't fix it, I'd look at the shocks or bushings. How many miles on your shocks? Have you checked them for leakage?

 

could be resonance. at that aproximate speed ur cars engine suspension n what not could be movign together in harmony....that would be why if u go faster it stops and if u go slower it stops, they stop vibrating together at the same time..could also be wheel balancing as said b4 check if the rumbling and shaking gets quicker as u speed up than wheel balance is most likely ur issue

 

Havent checked the shocks yet... Is there a certain procedure to do that? Thanks for the help so far.

Only tests I know is the push test.. push on the fender and see how many times it oscillates... it should be only 1 or 2 at the most and a visual test to see if fluid is leaking out of the shock, usually noted by fluid/oil on the shock body.

Other thing to consider is a bad tire, which is why I suggested rotating front to back... assuming the back tires are good.

Good luck... let us know what you find.

Im sorry could you explain "oscillates" please? lol sorry.

 

i know everyone is telling you tires or suspension, but bad motor mounts will also cause this problem, check all the rubber inside your motor mounts and make sure none are broken, or cracked.

also check your tires, look for bald spots or bubbles in the tires!

 

push down the front fender then let it go. It will come up and go down. If the shocks are worn, it wil continue to go up and down. If your shock is okay, the fender should come up and go down only once... twice, maybe. Is your suspension stock or after market? how many miles on them?

check for leaks on the shock body.

 

Make sure its not your spindle or bearing that has gone bad either and make sure the lug nuts are on tight ... if thats not the case, if you have a camber kit ... make sure the camber kit is not loose.

 

Suspension is GCs and tokico illuminas all the way around... Not sure how many miles are on em... I bought em used.
