131mirafiori forum

Hello, this morning I was driving my 131 at low speed, and suddenly a big noise from the lower part of the car arose. It's not from the engine, it just shows up when the car is moving and it's bigger and faster when the car goes faster. It's something like a big balm cricket under my car singing. Now the noise has become much lower and it mainly appears when I accelerate. Could it just be a bearing or it is more probable a transmission problem such as differential? It's not the rear brake, I got the two inspected and no issues. The differential shows something as a tac-tac-tac when the car is on the lift and I spin the wheels. But I forgot to inspect the wheel bearings, so I can't say where is the problem.

On two of my 131s I had a loud clicking noise from underneath which turned out to be the fuel line vibrating against the inside floor of the car. Check that yours is secured well and can't vibrate. If it's that .....it's an inexpensive and easy fix. Fingers crossed....

I'm still not sure, I think it should be something in the gearbox or differential, but it still works fine. The noise is still present but much much lower, and it's like a squeal of metal grinding.

Rear axle oil seal (one side). Had this problem when returning from 3MA13. My fix was to install another rear axle...

Fit Toyota axle problem cured & all future problems also ;)

By now the noise has completely disappeared, I suspect it could be something that will give me bad surprises, but as I have to do 60 kilometers every day with the car I cannot inspect, hope will give me no more trouble. Can the gearbox do such a noise and then stay quiet without signs of damage?

Record it and put it on youtube or something

I had the same idea but the noise is now too low to be recorded. Well, just wait an see what it happens...
