Andrew Chua Posted October 20, 2008 Share Posted October 20, 2008 As of the past 2 days, I'm beginning to hear a strange 'wonking' sound from my landie when it reaches 60km/h. If i hold steady at the speed (with the accelerator), i hear it continuously. If i drop speed or pick up, it goes away. if i clutch in, it's goes away. Free revving of the engine in neutral, moving and stationary does not create this sound. Is this a sign of failure of anything major in the gear box or is something screaming for attention that it's not getting? Could it be a sign of vibration which could mean the mounting? Clutch plate? fork? release bearing? I'm starting to get a little frustrated of late as various bits seem to be breaking down one after another. on the exterior, my landie looks like she just left the showroom a day ago, but on the inside it seems like there more than what is desirable.

yellow Posted October 20, 2008 Share Posted October 20, 2008 Check your UJ joints on the props. They could be worn and throw off the balance of the props. Oh, adn do not wait for it to go bang, get underneath and find out... Quote Link to comment Share on other sites More sharing options...
Andrew Chua Posted October 20, 2008 Author Share Posted October 20, 2008 ok, i'll have a check when i arrive at the office tomorrow. the car park floor is cleaner there as it's new. So basically i just crawl under, grab the prop and wiggle it. problem might be on the front one. what's the part number for the UJ? should i just change all 4 of them? any recomendations to what brand should i go with this round? planning to ship in a fuel pump for the vehicle soon, so i guess i better get all my bits in together.

roybatty666 Posted October 20, 2008 Share Posted October 20, 2008 make sure your hand brake is off and your on the flat as that can wind up the slack in the props it it resting on the brake I had a rather nasty sound at 40mph which was a dead rear prop joint and that also went away when speeding up or slowing down Quote Link to comment Share on other sites More sharing options...
yellow Posted October 21, 2008 Share Posted October 21, 2008 As for parts, especially drivetrain related, I believe you get what you pay for. I'd go for genuine UJs and make sure they have a grease nipple. Changing is easy and can be done by carefully using a set of spanners and Land Rover Tool #1 (Big hammer) Quote Link to comment Share on other sites More sharing options...
Andrew Chua Posted October 21, 2008 Author Share Posted October 21, 2008 It seems that there are 2 sizes of UJ. one the 75 and 82mm. i believe it's the 75mm but i'm really not sure. Seems like some people recomend the hardy splicer (GKN) UJ. Are they better that the original or will I be ok with the genuine bit? Quote Link to comment Share on other sites More sharing options...
western Posted October 21, 2008 Share Posted October 21, 2008 HS & GKN are original parts suppliers to Lr so either will be fine. Quote Link to comment Share on other sites More sharing options...
Andrew Chua Posted October 29, 2008 Author Share Posted October 29, 2008 ok, i've put the entire truck up on the ramp and ran all the wheels lifted off the ground together. the sound seems to be coming from the front end of the truck. engine was too loud to hear while under the truck. ok, sounds pretty dangerous, but i'm still alive. the U-joints are all ok and there's no unusual vibrations when driving. bearing? or differential as the next suspect? or what else could possibly be wrong. the guy at the workshop has no idea too. shall i remove the front prop and try driving around on rear wheels? will i screw up anything this way? the strange thing i noticed is that the rear wheels spin faster than the front when they are all lifted off the ground, so there must be like 60/40 split at the t-box?
