My 99 Land Rover D2 (114K miles) has a vibration around 75 mph.

I have replaced the tires, wheels, rotoflex (rear driveshaft part) and front driveshaft. Still does it... I haven't had the front driveshaft out in a while, but if I recall, it doesn't vibrate with the front shaft out. But, I was thinking that the vibe may be being amplified by the front driveshaft from somewhere else.

I feel the vibration in the seat as opposed to the steering wheel. It's not bad but it is annoying enough that I either drive at 70mph or 80mph when on the interstate. It rides perfectly smooth at 70 and 80, even 90 but at 75 it has a vibration. I am thinking about taking the rear driveshaft out and seeing if the vibe goes away. Should I consider replacing all of the bushings as well as the motor mounts and trans mounts?

In the words of Larry the Cable Guy "I am more frustrated than an Ethiopian watching a doughnut roll down a hill."

Buddy of mine had a new van with a vibration they finally traced to the internals of the tranny. They said there was no fix for it and it fell under the normal tolerances. Still going at 70,000 miles and annoying him everyday

Any chance the driveshaft is out of balance???

I had a vibration like that once in a car and it was a warped brake rotor and it only showed up at high speeds. Around town up to 60 mph it never showed up.

I had some intermitent vibration from old motor mounts on my jeep. Usually, whey there's vibration, I start looking at balancing the tires and throwing money in that general direction.

Thanks for the replies gents...you too Easty! :D

I am leaning more towards a driveshaft issue. Could be a balance issue, could be a slightly bent driveshaft. :confused:

Here's a scenario...
What if I pull the rear driveshaft and drive it and it doesn't vibrate. Then I put the rear driveshaft back, remove teh front and drive it and find no vibration? What would that mean, a problem in the transfer case?
I am pretty sure that if I remove teh front driveshaft the vibration goes away. I am thinking about removing the rear only and seeing if the vibe goes away.

You may try getting it aligned.
BTW ran across a 95 discovery- lthr, roof rack, brush guard, lift, off road tires, hella lights, but needs work (doesn't say what kind of work) $3500.00 whats your thought?

Walk... No run away! :D

No, seriously, what kind of work does it need. You should be able to find a '95 D1 that needs no work for around the same price.

It seems if you start removing members or changing the stock configuration for your experiment, you change the system's natural frequency. You might not be alleviating the problem during the test, you just might be changing the point at which it resonates. Maybe that is all you want. I am no expert...just came to mind.

I know what you are saying.

It could be that the driveshaft is amplifying a vibe from the front diff or something.

Yes. Or...on the other hand...it could be that the overall vehicle has so much dampening mass that the presence of a shaft makes little difference. Again, I defer to someone who studies this sort of thing.

If you call on it, let me know what they say. I may be able to give you an idea of the cost for fixing/replacing.

The main problem with these vehicles is that I can't just go down to Auto Zone to pick up a part. I have to either order it from an online vendor or buy from the stealership.

Aside from that, the vehicle is easy to work on.

Just did.. Got the Mrs. All she knows is something about low compression in one of the cylinders..

New tires......??..... Are you certain they balanced them correctly.... Did it have the vibration previous to the tires?
Why did you replace the wheels....... Are you spinnin 22's on it or something?

Yes, you would get a vibe if the driveshaft(s) had a ding in it, or bent, or out of balance. Ever take it off road?

It has been off-roaded, but nothing serious and no rocks.

I replaced the wheels because I like the look of these better.

The vibe has been there through 2 sets of tires, 1 set of wheels, and 3 front driveshafts.

Oh, probably needs a vavle job then. Pretty common on those engines. Doing most of the labor yourself, it will run you nearly $1000. Closer to $2000 and up to have someone do the work. I think the book time for LR is something like 15 hours.

$3500 is a bit high for a '95 with low compression, IMHO.

I haven't read all of the posts, but have you checked the U-Joints in the driveshaft?

Not on the rear driveshaft...

Seriously,

Get a jack.
Jack up the radiator cap
Drive the truck out from under the cap.
Drive a Chevy under the cap.
Lower cap and clamp securely.
Problem solved

More of a tapping than a vibration, but having had one go bad, I feel compelled to at least say "u-joint."

Ric

could be ujoint
tires
driveshaft imbalance
or... I had this happen once on a tight but hi mileage 4x4... Transmission slippage... yep it sounds weird but we diagnosed til we were blue in the face and finally ponied up the bucks for a transmission rebuild and the vibration or shudder was gone

I suppose you could rule out the tranny by getting it up to 80 and then putting it in neutral and coasting down to 70:) (okay, maybe not, but that's all I got:))

Does it matter what gear you are in.

When is the last time the tires were rotated (diagonal).


OR, like Ric suggested, replace everything but the radiator cap:)

I have an '03 Suburban with a vibration at 40mph and a more intense vibration at 70mph. Wish I knew the source.

That sounds like driveshaft, especially the 40mph vibration.

Aside from the wheel bearing I had replaced on the Exploder, the only other issue I had with vibration was an out of balance wheel due to a large clump of mud that was on the inside of the wheel (caused a vibration at hwy speeds)

I found the source of vibration finally on my 97 K1500 Suburban

NEW rotors & NEW calipers

found it like you're talking about...... remove each drive shaft & test drive

vibrated either way:rolleyes:

had tires "road force" balanced multiple times....(different places)
even went as far as borrowing a buddy's tires & wheels to experiment with.

not saying that's your problem, but a vibration will drive you nuckin futs:rant:

All right Beau, report back after the driveshaft experimentation......
The vibe has been there through 2 sets of tires, 1 set of wheels, and 3 front driveshafts.
After this comment, I am ruling out unbalanced wheels, and front shaft. :confused:
