My car is shaking in 4th and 5th gear

[George]

Hi everyone 

New member here 

I have a Honda Accord estate 2.2 IDTEC Type S 60 plate and from couple of weeks ago my car is shaking really bad but only in 4th and 5th gear, I can feel a slight vibration in the 3rd gear as well but not all the time, I've been told that it might be the crankshaft pulley. Anyone else had the same problem? 

Thank you

Hi.....welcome to the Forum

 

Is it vehicle speed related rather than gears and revs?

e.g. is it at 60mph and then disappears as you get to about 70mph

If so, then it is a static wheel imbalance and need to balance the front wheels

Hi, thanks 

The car is shaking only in 4th and 5th gear between 1700 and 2000 rpm, nothing below 1700 and over 2000 rpm

[Trevor]

can you estimate approximate road speed when it occurs?

[George]

It's somewhere between 40 and 60 mph, after that I can feel just a slight vibration. This is what I've been quoted by a local garage but I think it's a lot of money for a drive shaft. And sorry for the late reply but I've been busy lately

If it is the driveshaft that is out of balance then you can prove this by placing a jubilee clip around mid way along the shaft and see if this cures the imbalance.
You can adjust the point of balance and even add a washer or coin under the clip to counterbalance the shaft.
We used to use this technique on propshafts to find the imbalance and then weld a weight onto the shaft in the correct place
