Hello there,

I´ve been away for quite a while since I had lost my Rangie to my ex-wife but now it´s with me again! :D

I don´t how what was done to the car but it happens that both CV´s are making a lot of noise when manouvering and tight turns. Diff seems to be ok and oil levels are all right. I thought it could be due to the centre viscous coupling being seized so I did that test.

I raised the rear right wheel and tried to turn it. It did turn but I felt a lot of resistance. I could turn it by myself but I had to apply quite some force to do it.

So I was wondering if anybody has done this test and had a similar experience. Any feedback is welcome!

cheers!

Remove front driveshaft and use big breaker with socket an flange nut, 32mm I think, turn clockwise and coupler will turn with much resistance. I cant remember the specifics but its something like at 40lb ft torque it will turn 1/4 turn in 30 sec. Test is done with wheels on ground. If coupler is seized it will not turn at all. If you want to drive you can leave driveshaft off. I'm sure if the ex drove for some time wilh bad coupler it damaged cv joints.

The viscous drives the front propshaft. Best to try the slow turn test by jacking a single front wheel up. Leave the vehicle in park. The rest is pretty much what you did with the rear. Not sure all the details of your test, but with the tranny in park you shouldn't be able to slow turn the rear wheel. :think: The feel to the slow turn is exactly what you describe, it takes a lot of effort to turn the wheel, but it will slowly give way and stay in the new position if your viscous is OK.
