guys-(01 discovery2 se7 104k) i just noticed a clunk when selecting gears from: p - r, n - r and d-r. so i started looking around/messing with things and found that in neutral i can crawl under the truck and wiggle the front ds about 1\4 inch. i just had ALL ujoints replaced/rebuilt front ds with greaseable joints so i dont think its that. help?

 

More than likely normal driveline slack.

 

Check all four tires and make sure that they are at the same PSI.
When I get a low tire I get a severe drive line clunk.

Otherwise come play and noise is normal for a full time four wheel drive that has all gears and no clutches.
85w-140 gear lube will help quiet things down too.

 

hey thanks guys! i will check tire pressures.all 4 tires should be the same pressure? 28f/46r is what factory calls for. im not trying to be a jerk but how does tire pressure relate to driveline slack? im new to land rover but im willing to learn and turn.

 

I run mine at 40 psi all the way around.
It helps MPG.
LR says to run soft in the front and hard in the rear for handling, when it is loaded the rear will need the extra air.
Soft up front makes for better tracking going down the road.

You want to run at least 35 psi on all fours.

A soft tire is smaller diameter than a hard tire because the side walls will not be standing up straight.
Make sense?
So while the fronts are making 300 revs per mile the rears are only making 250 revs (making numbers up here to make my point)
With the different tires spinning at different speeds and since all four wheels are connected all together something has to give.
So the driveline gets bound up and it puts extra wear on it.
The driveline in these trucks is all gears and nothing but gears, gears wear, gears bind, gears are reliable, I like reliable.
But they need special attention.

 

How long ago did you change u-joints? They need to be greased often. I had a u-joint go out because of lack of grease to one of the bearings. Y

 

You need to make sure grease comes out of all four seals.

spike- thanks for the breakdown and not flaming me for stupid questions. i understand now, thanks.

willie- front and rear joints were done about 800 miles ago. is it possible that shop didnt grease enough? im not sure, but i know what im doing tomorrow...if would only stop raining...thanks

 

It could not hurt to grease it your self to make sure. I think shops are good about greasing thing. But not the drive thru lube places , stay away from those. Also check the rear u-joint.

yeah im gonna crawl under tomorow and do it anyway. it cant hurt and will give me a piece of mind. im gonna need a grease gun... and what grease should i use? and i never take anything to a quick lube type place.

is there a way to grease the centering ball that i had replaced also?
