My car suffers from a noise, which can only be described as low rumbling sound on acceleration or under load. It mainly happens in 1st and 2nd gears. I have had the driver side, drive shaft replaced as this was noticed to have play whilst the service work was being carried out, thinking this could be an issue. After this was completed the noise was still present. I have not tried the passenger side drive shaft as yet.
I am at a loss because I don't know if this is could be gearbox, final drive related issue or something worse. All engine, gearbox oils were checked and appeared to be ok.
Any thoughts on this issues would be greatly received.
