140 Speedometer sensor

94 Sclass 140
I understand there is a speedometer sensor somewhere near the right front wheel of a 140. Need to know exactly where?

No the light is not on but sometimes when I hit a bump with my right front tire the speedo will drop to zero and stay there. I can restore it by hitting another bump with the right front tire so I think there might be something loose.What mite it be?

The ABS signal is generated by the LEFT front wheel speed sensor.

If the ABS lamp is not ON...then the wheel speed sensor is GOOD!

You are heading in the wrong direction. Unless the ABS lamp comes on DON"T blame a wheel speed sensor.

then why sometimes if i hit a bump the speedo goes to zero and by hitting a bump again I can restart it.
PS sometimes when I start my car the abs light stays on and by restarting it goes off.
