I've never dreamed of going over 80, never touched 75 myself. My Disco is my first car though...

 

Remeber that speed kills, or is it crack kills? Anyway pull up your pants and drive slow.

 

Personally, I think I should disable 3rd and 4th gear in High range. You don't need those off road.

 

I always off road in 2nd gear. 1st gear when going down a long steep grade.

 

Ive done 110 a couple of times but not to often mostly I cruise at 90, 95 Milles Tops Now Im goint to keep below 85 if I can find the source of the Humming sound... RPM is just below 5000 at 95 ,,, At 110 I don´t remember mostly I was Just holding on.

 

I just had my front output shaft yoke replaced as it was the cause of my vibration

 

I went to a LR dealer To check the Rotoflex, Transfer Case, and Diferentials ( Oil Level and Quality ).
They said everything was fine , Oil in the rear Diferential seems a Bit Burned ( Black ) They did not recomend changing the oil.

never the less I Just Bought a rotoflex on Ebay ( http://i2.ebayimg.com/08/i/001/12/87/05e9_2.JPG) And am thinking on Buying a rear Drive shaft with greaseable U Joints.

The tyres have about 1/3 life Left and seem fine but they mentioned that could be the source of the vibration.
I am starting to guess a Little and guessing is always expensive if you are not lucky.

What would you guys recomend doing first.
Im also starting to feel the stock crisis and $ is a bit short now.

 

I would buy new tires. If you wanted to save money then drive slower and make those tires last longer. Not to mention the gas that you will save by driving slower.

 

If you just bought a new rotoflex, there's no need to spend more money on a rear drive shaft. The rear d/s has grease zerks by the t-case and slip joint, that's it. The roto "replaces" the u-joints that would be at the rear of the d/s. If you destroy a roto due to a lift (usually 3" or higher) then you should do the rear u-joint conversion.

 

I drove my 2004 Disco to 85MPH just to check it out but I sure would not want to cruise at that speed. I found the handling a little disconcerting at that speed, thus I cruise at 70 and all is good.
