Outer Limits 4x4 Board

i had my lt95 rebuilt about 12 months ago, - new main shaft, a few gears and new sincros and shims, and well, basically anything that didnt look new was replaced. the transfer and center diff were deemed ok but needed shimming. The shifting is nice and backlash is, well, its a landrover...... Anyway my daily driving involves alot of hi way kms and when i'm traveling at speeds over 100 and backing off there is a large rattle (i can feel the floor vibrating), until the drive train takes up slack. where should i start looking? i have replaced the unis in the shafts and the sound is definately coming from the gearbox/transfer area. Any sudgestions where to start looking?

Could it just be a mount coming loose or shagged???
I'd just be poking and proding (heavily) in the hope
I'll find something a miss. I'd hate to start pulling things
out when there's no need.

I have an LT77 gearbox with an LT230 transfer and mine does exactly the same thing.

Sounds like someone rolling a steel drum down a hill full or off-cut steel. Most off putting.

I suspect there's too much endfloat in the transfer case allowing too much play in the gear train.

I plan on changing the oil to see what drops out plus to see if fresh oil improves it.

Have you tried backing off the brake shoes from the handbrake drum?

If the shoes are too close, they can cause a similar problem to what you described, but in my experience it has occured at low speed, when you back off.

I had a similar problem in my lt95 when backing off in most gears, ended uip being that the end floats were stuffed.

Bush65,

The hand brake is working fine.

Mudlust,

I tend to think you're right.

You can get the rattle to come and go by letting the throttle float between accelarate and coast. The rattle happens as soon as you lift off the pedal. If you let the speed decay without lifting right off it doesn't rattle.

Looks like another job to do.

mines been doin this for sum time now

ZF auto with viscous tcase....

what shoes? i pulled them out 4 months ago!!! i broke one of the retaining clips holding the shoes to the bacling plate and pulled them out as a temporary thing to stop them rattling. Gotta find time to put them back together.

Mudlust, which end floats are you refering to, the box or transfer? can you check this without removing the box?

are the end floats just the shafts at each end with the roller bearings cause that was one of my symptoms as well
