Sidshk Posted October 2, 2019 Report Share Posted October 2, 2019 Update Today morning while driving 4X4 central diff lock light was flashing and 2 wheel light was off, so i pulled up and restarted car and it went off But there is steady vibration after 2500 Rpm , or above 95 Kms speed Any suggestion what is causing it ? 2 Link to comment Share on other sites More sharing options...
Frederic Posted October 2, 2019 Report Share Posted October 2, 2019 Looks like your Central diff is still engaged. That probably causes the vibration while driving it on road (not advisable !). How does the car drive in 2WD ? 2 "Go as far as you can see; once you get there, you'll be able to see further." Link to comment Share on other sites More sharing options...
Frederic Posted October 2, 2019 Report Share Posted October 2, 2019 Copied from earlier post: You'll find lots of information on the wise web about this common Pajero issue. it's either: 1) The solenoids which are located in the engine compartment 2) The vacuum hoses between solenoid and the diaphragm 3) Stuck actuator (piston) that engages or disengages 4WD 4) Vacuum operated diaphragm 5) Sensor on the transfer case. For some more information (there might be slight differences between the Pajero generations) http://4wd.blogeasy.com/article.view.run?articleID=318776 PS Do note that: * On the Gen2 and Gen2.5 models (like mine and @Gaurav) the 4WD engaging is done purely 100% mechanical, so the sensors cannot cause real issues, they are only there as feedback for your dashboard indication. Only the switching between 2WD and 4WD is done with vacuum actuators. * On the later Pajero models, all functionality of switching between 4Lo, 4H, 4HLC, or 2WD is done by solenoids, because your 4WD shifter is not a mechically engaging unit. These models are more prone to issues, and the blinking lights really do mean something went wrong. 3 1 2 "Go as far as you can see; once you get there, you'll be able to see further."

The Flashing Light went off and 4X4 display went to normal after re start There is continues vibration above 95 Kms at 2WD as well 2 Link to comment Share on other sites More sharing options...

Just by quickly accelerating you will see if all tyres spin, or only the rear ones. Driving in 4WD on road will give more vibration. 3 1 "Go as far as you can see; once you get there, you'll be able to see further." Link to comment Share on other sites More sharing options...

Frederic Posted October 2, 2019 Report Share Posted October 2, 2019 2 minutes ago, Sidshk said: Do you mean 4x4 is engaged even if the lights are off ? Yes, that is definitely possible and could explain the higher vibration. 2 1 "Go as far as you can see; once you get there, you'll be able to see further."

Gaurav Posted October 2, 2019 Report Share Posted October 2, 2019 Just now, Sidshk said: Do you mean 4x4 is engaged even if the lights are off ? Yes and best way is to engage and drive 100 meters, then disengage and drive 100 meters. Do this few times if needed and see if your 4x4 is completely disengaged and vibrations are eliminated. In lever base 4x4, sometimes it gets partially engage or disengage and release after few meters of driving. Reasons could be all of the above that Fred mentioned. 3 1 Let's root for each other & watch each other grow. Link to comment Share on other sites More sharing options...
Sidshk Posted October 2, 2019 Author Report Share Posted October 2, 2019 Thanks to @Frederic & @Gaurav i will try the above method, as of now we are checking for Error code with OBD scanner if there is any error with the system. 3 Link to comment Share on other sites More sharing options...
Frederic Posted October 2, 2019 Report Share Posted October 2, 2019 One GOLDEN tip for any Pajero 4x4 that doesn’t go off-road often: once a week, switch between the 2WD, 4H, 4HLc, and 4Lo setting for while. The solenoids and vacuum actuators tend to seize after a while when not being used regularly. 3 1 2 "Go as far as you can see; once you get there, you'll be able to see further."
