Orrible rattling noise

Please help!!!!!!

Yesterday the 90 started making a horrible rattling/knocking when the engine is idling. The noise disappers each time the clutch is depressed, and is not noticeable when driving, only when idling. The 90 has an LT77 gearbox with a reconditioned lt230 transfer box and 149000 miles on the clock.

the noise got noticeably worse each time i stopped at a set of traffic lights. and is even worse today.

What is the noise caused by, and is it anything to worry about????
Ta in advance for any help or advice.

Got to agree with YD on that one. Mind you at least you can drop the box on yer 90. Unlike that feckin thing of mine.

ta you two
Is it expensive, and is it a ****ing horrible job to do????

yella · Feb 18, 2006

gearbox is heavy if you are on yer own underneath on axle stands but the bearing costs about a fiver

4 hour job if you just pull the box back a bit

yella · Feb 18, 2006

6 hour if yer stop for tea regularly

slob · Feb 18, 2006

6 hours 30seconds if you have a shag as well

yella · Feb 18, 2006

30 seconds, blimey you take yer time

I had the same horrible rattling noise coming from the LT85 in my Santana. Changed the clutch release bearing and the bearings in the gearbox and now the rattling is gone. It was either the clutch release bearing or the rear layshaft bearing, or both, as these were the only bearings that were damaged.

ta for the help so far
So its the thrust bearing that is knacked and causing all the racket?!?
I know the release bearing for the clutch is in the bell housing between the engine and gearbox, but forgive me for being thick, but where is the thrust bearing, is that there too????

yella · Feb 22, 2006

its the same thing mate

Cheers ta
I reckon i had a bit of a blonde moment

Gearboxes are still a bit of a strange phenomenon to me

GRUNT · Feb 22, 2006

It's the same thing. According to Haynes its a three spanner difficulty which is "difficult, suitable for experienced DIY mechanic" . They also reckon it's esier to remove the engine to do it rather than the gearbox!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I've done plenty of thrust bearings in my time but not on a Landy, taking the engine out to do it seems a bit drastic!!!!!!!!!!!!!!!!!!!!!!!

GRUNT · Feb 22, 2006

Hey up Yella, Toots, where did you come from, thought I was in here by myself.

tootle_the_white_90 · Feb 22, 2006

A mate of mine reckoned it would be best to do it by taking out the engine too, though he seemed strangely reluctant to help when i asked him
