Why does a starter "bounce"?

I can’t answer your question definitively, but I’d like to give you evidence that your theory of the engine overrunning the speed of the starter gear via compression release is not correct. (Don’t ...

Why does a starter "bounce"?

I have just tried adding power to just the solenoid on a spare starter motor that I have on hand (this is one off a Jaguar, but I would have thought it would behave the same). There is no way I would ...

Grinding noise while driving

The diagnosis that you're done pretty much narrows it down to something between the output of the transmission and the wheels, including the brakes. You can eliminate the brakes, by lightly applying ...

What could be causing a grinding noise when car accelerates quickly?

After arriving on the scene, first I established the scope of the problem and areas affected. The noise did not happen if I reved up the engine rpm in park. so we can rule out a valve bearing or ...

2011 Subaru Outback grinding noise when starting car

Going by the sound that you have posted I would think it is the starter gear being slow to retract from the flywheel and the teeth getting hit by the teeth on the flywheel as the engine speeds up and ...

Strange case of low-speed squeaking / grinding noises after new tires / alignment

I'm not positive this is your specific defect but it's something to be aware of. It's quite possible the tire shop futzed your tire pressure sending unit inside the tire and now the pressure sending ...

Wheel noise that's evading me

Given the lack of play and the fact that it's only really present when turning right it sounds very much like wheel bearing to me.

Girinding noise /sticking breaks even after installing new caliper, rotor and pads

I made a fool of myself. I took my car to a mechanic and he said I had placed one of the brake pad front-side-back.

2011 Subaru Outback grinding noise when starting car

Thanks for the audio. By hearing the sound it doesn't seems that there is a problem with the engine. Neither there seems to be problem with the starter mechanism. At temperature below 25-C/77-F the ...

Strange case of low-speed squeaking / grinding noises after new tires / alignment

May also be very possible that your brakes have gone out. When your brakes wear they rub the rotors causing the grinding and the squealing due to it being metal on metal. You want to have this looked ...

Why does a starter "bounce"?

Thanks @MTA for debunking the compression theory. https://mechanics.stackexchange.com/a/91092/10721 I don't have to tools to measure that. And @HandyHowie almost got it right. https://mechanics....

Strange case of low-speed squeaking / grinding noises after new tires / alignment

When (un)mounting wheels people sometimes touch the dust shield(?) (the one from this question), bending it out of shape a little. The piece may subsequently touch the inner part of the rim slightly ...

Grinding/rattling Noise from engine accelerating on both idling and driving Suzuki G10 3-cyl Engine

The knocking sound (if that is the sound you are talking about) is likely coming from the inside of the engine. To properly diagnose the exact wear that is causing the noise will require some ...

Do you have to machine the crankshaft after a spun main bearing?

TLDR: To do it right and not have to do it again in a month (or possibly right after start up), the only way to fix this is to either pull the crankshaft and have it turned, as well as check the ...

Do you have to machine the crankshaft after a spun main bearing?

The bearing material is softer than the crankshaft, so any imperfections will chew up the bearing. There is no way you will get an accurately cylindrical shape with the correct diameter and surface ...

Constant grinding from rear wheel?

It turns out that the sound was actually the rotor backing plate. But it was not on the outside of the place where it can be bent out pretty easily. I had to take the rotor off to access the inside ...

Grinding noise in rear after replacing front rotors/pads

The problem was, in fact, the rear drum brakes. They were pretty worn down. When I changed the front brakes, there was more pressure in the system (when I pushed onto the brake pedal) going to the ...

Brake rotor grinding when moving after installing new pads /rotors

Brake disks should be machined pretty much true with virtually zero run-out. Sometimes however they're not perfectly machined and they'll have a very slight bit of run-out in them. This is whats ...

Fiat Stilo 1.6 2003 - grinding when shifting

This sounds like synchronizer problems. What these do is match the gearbox rotation speed with the engine speed. Before these were around, you had to do what's called double-clutching, lest you hear a ...

Fiat Stilo 1.6 2003 - grinding when shifting

A possibility is that the clutch centre plate is not moving on the gearbox input shaft and then "dragging" on the flywheel which makes it hard to engage gears. Sadly the only solution in that case is ...
