Hello,
I recently bought an LR (santana) 88 series 3 from 1978.
it has a problem with the transmission. It makes a loud, dry noise, as if someone were hitting with a hammer.
Noise appears according to speed. The faster the blows sound faster.
When you go slow it doesn't make noise.
I do not know exactly what it can be if the transfer case, gearbox, transmission shaft and crossovers, differential.
I have done calculations and I believe that each time the blow is a wheel revolution. (more or less, 1-5 strokes per second, depending on speed)
He does it in the 1-2-3-4 march.
TRANSFER CASE:
-In the short transfer it is only heard very slightly in 4th gear with the engine at full throttle.
-With the long ones, he does it in all. When you go slow, no. It does so at 20km / h and the noise is progressive with speed.
-With the neutral of the transfer and the engine at full throttle it does not make any noise.
When you go fast (20-30km / h) with the clutch on it makes noise.
If you tighten the clutch (20-30km / h) the noise disappears.
This confuses me a lot because I thought it was the drive shaft and the cross braces.
At first I thought it was the front differential and removed the front driveshaft.
The noise seems to be from the front but, the truth with so little isolation, I don't know where it comes from. I am not ruling out the rear axle.
I have it 300km from where I live and the next time I go I want to have some idea where to look.
Can somebody help me.
Thanks
