Anglo-Frenchman Posted April 7, 2006 Share Posted April 7, 2006 Having recently had an issue with a vibrating front prop-shaft UJ due to poor (non-existent) lubrication after the vehicle was left un-driven for a number of years, I find that ocasionally I get a slight vibration at around 80km/h which can be driven through and vanishes altogether. In an attempt to identify if this is the culprit, I thought about removing the front prop-shaft to see if this vibration was still present but wondered if this might damage the transmission in some way what with the permanent 4WD.

Big Watty Posted April 7, 2006 Share Posted April 7, 2006 Shouldn't be a problem - just means you need to drive with diff lock in Quote Link to comment Share on other sites More sharing options...
northernchris Posted April 7, 2006 Share Posted April 7, 2006 Did the very same with mine to try and find a problem,it did the trick. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted April 7, 2006 Share Posted April 7, 2006 Just remember that all the power is going through one diff so don't get too carried away with the throttle! You will find you get horrible backlash as I did this once when trying to find the same problem, but you can do it OK and it will help isolate the problem.

Anglo-Frenchman Posted April 8, 2006 Author Share Posted April 8, 2006 If the vibration does turn out to be the front prop - whats the best solution. Is it a case of renewing both the UJs? Quote Link to comment Share on other sites More sharing options...
western Posted April 8, 2006 Share Posted April 8, 2006 If the vibration does turn out to be the front prop - whats the best solution. Is it a case of renewing both the UJs? Yes, change both & grease the sliding joint as well, about 4 or 5 strokes from the grease gun on each grease nipple will be sufficent.

Anglo-Frenchman Posted April 8, 2006 Author Share Posted April 8, 2006 Thanks Ralph. What's the most reliable way (if any) to check for play in the UJs while in situ? Quote Link to comment Share on other sites More sharing options...
sgnas Posted April 8, 2006 Share Posted April 8, 2006 Thanks Ralph. What's the most reliable way (if any) to check for play in the UJs while in situ? Chock the wheels, take the handbrake off, out of gear, get underneath and start twisting and lifting to find any play. BTW handling in RWD only is more than interesting, it's horrendous. FWD is even worse. Quote Link to comment Share on other sites More sharing options...
Anglo-Frenchman Posted April 8, 2006 Author Share Posted April 8, 2006 Thanks very much for the advice. I only intend to drive it far enough to establish where the vibration is coming from. Quote Link to comment Share on other sites More sharing options...
