the vibration really is bad around 60-70 and then near 80 it starts to smooth out, i have new tires, i tried having them rebalanced, i tried rotating them and just no change. anyone have any ideas. thanks... | ||

David, You need to provide the group with a bit more info: #1 How Many Miles? #2 Service habits? #3 What have you looked at? #4 Any Leaks? #5 Anything Missing? | ||

Check your rear rotoflex coupling. I had a vibration at that speed and replacing the coupling fixed it. | ||

sorry guys the truck has 70,000 miles on it, i have the rover dealer change the oil and check out everything every 6,000 miles, never had any major problems, no leaks.. as for the rotoflex coupling i have read many posts about that, but mostly all of them are on older disco's.. where is the best place to find that coupling and is it hard to change, i do all the minor repairs to my truck, is something i could do? | ||

David, I have a 2001 D2 and mine started vibrating around 51K. It is located at the end of the rear driveshaft. It is really easy to replace, just loosen all the bolts (6) around the coupling and slide the driveshaft forward on the slip yoke, you can then put the new one in. Here is the tricky part, there is a pilot bushing you are suppossed to replace along with the coupling. The bushing is inside the end of the driveshaft, and it is really a ho to get out. I slid my shaft off of the slip yoke (please dont do this, it is a bear to get back on). I ended up taking my air tools out and cut it with a chisel. Maybe someone else will chime in about this and tell you not to worry about the bushing. I dont know how important it is but I had already ruined the existing one trying to get it out before I realized how hard it would be. I ordered mine from Mike M. He posts on the board. I got mine for about $65 with the bushing. Besides checking for any loose bolts I cant think of what else it could be. Usually tire imbalances are gone by 70 mph. Do you hear any sort of low frequency noise when it happens? | ||

Sure it's in the rear? Could it be the non-svcble u-joints? The joints run near the cats which heats them up causing the grease to melt out. A friend of mine just replaced his whole t-mission due to a u-joint failure at 75ish mph. I thought the vibration was in the rear end but it was the front prop shaft. Just a thought. | ||

David, I have a 2000 DII like you. I also just passed teh 70,000 mile mark. Here's my story............ At 60,000 installed OME HD 3" lift (springs and shocks). I started noticing the vibration at about the 65,000 mark. I started my investigation and read on this board where the front drive shaft is a very vulnerable item. During my fluid changes at 68,000 miles while the mechanic had it up on the rack we checked the front drive shaft and it appeared to have some movement in the U-joints. I call Bill at Great Basin Rover and I go ahead and decide to replace both my front and rear drive shafts. To make a long story short, problem fixed. I would submit to you that you have a front drive shaft issue developing. And like Jack said, if it's not addressed now it could end up costing you a lot more than you want to deal with. Tell Bill at Great Basin Rover that I told you to call. We've been on the phone a lot hear lately. |
