Its got to be the engine or G box foundations.
If in stationary engine revving it doesnt come then its the gear box. Should also check the Universal joint of the prop shaft.

Your differential is on its way out get the differential opened and you might have to change the bearings fast if you continue to use the car in this condition it will become werse later on.

Sorry to suggest, PLEASE do not touch the diff till you have checked the foundations and U joint. If at all the diff is to be opened get it done by a Very Very good workshop, more importantly a good mechanic on the job. I have very bad experiences with opening the diff in Mercs of that generation, the Hum remains for life!!
Mr Sirkar why would the diff bearings give way? No oil, Non use, or? since this doesnt look like a car with a few lac kms.
You have some good mechanics with experience in 123's in Bangalore.

I forgot to add.The 300D with the 5 speed gear box ha a manufacturing defect with the gear box.So the thing which we did to two cars were changed their gear boxes to 4 speed and the problem went and in one car it was having a similar problem in which we changed the differential bearings.So i would suggest you need go for a 4 speed gear box the nboise should go down if it dosent then you have to get the bearings checked out.The 300D also came with the 4 speed so you need to look around for a gearbox and it should get sorted out.

Well normally they don't give way that easily but it depends on how frequently the oil is changed and if the car has had a history of being used without oil.It also depends on the quality of oil used.We don't know what the earlier owner did with the car.

The car has had a good maintainence record as informed by the previous owner. the day i picked the car i did check on the gearbox oil and the kind of oil used was fine. i would want to hold on to the 5 speed gear box and try with the option of differential bearings

Well i would suggest make the gear box transplant the first option and then the differential.It may be that you change the bearings and the noise still dosent go but i would advice you to go systematically.


You could do some thing to see if its the gearbox or the differntial.start the car and ideal it for some time then drive the car and then after that accelarate on neutral and see if the problem happens or not.If it is happening then just put your foot on the clutch pedal and see if the noise goes down or goes completely.Do post your observation.

P.s. Do checkout the cluth and replace if its wearing out.

I will completely agree with Scooby here dont touch the differential> it does not appear to be the problem.

I would like to seriously disagree with you Indrojit. Firstly IMHO, the 5 speed is a fantastic gearbox and had no trouble whatsoever, leave alone a manufacturing defect. There aresill cars which are running perfect with the 5 speeder wthout an aorta of a problem, I have owned a few 300Ds in the past to corroborate the fact. Secondly swapping a 5 speed with a 4 speed is not the answer an is a definite no no in my books. Of course thats my opinion.

A differential vibraion and sound does not go off at varying speeds, it just stays there forever. With increase of speed, it stays the same and in most cases it increases and just not vibration, there will be a humming sound, very peculiar to the differential problem only as pointed above. Just get a good mechanic to look at it. I feel at the most you will have to change the two engine and one gear box mounts. That will take care of the vibration. Then as Scooby has suggested it might be the U joint bush but again if that is the problem, it would be coupled with a slight tug and thud which is again very peculiar to this kind of problem. you can feel the thud very distinctly.

It might not even be the gearbox mount problem, may just be the engine mounts on their way out or vice versa.

I would not touch the differential if the humming sound is not there at all. I would also throughly check the clutch, clutch cylinders and wheel bearings, though i still feel by what is said that it is a simple problem of the mounts. Remember, change all three together, never change just one or two. A good mechanic will tell you the problem just by taking a short test drive. Sould not take more than a day and should not cost moe than 4.5 to 7K for all three mounts. Im not sure since i have not bought these for a few years now. Very easily available too.

Change the filters, both oil and diesel with the mounts and see the 300 fly. With a 5 speed gearbox, whic h is the overdrive, the highway run turns into a dream.

Hi BSA was this car ever owned by the Gowda's? Mukund Gowda went to boarding school with me in the 80's and he had the exact same car with headrest etc at the back and same color. His granddad was some Minister in KA/Bangelore not sure if the same Deve Gowda family. This looks like the exact same car. She looks like she has been in a time capsule great buy and keep her that way.

Suggestion of changing the Original Gearbox, and that too from the 5 speed one to 4 speed, and opening the differential to check bearings etc are very Bad suggestions. Specially for such a Well looked after car. If this were a car out of Delhi/north, IMO, yes anything could have been possible but not a car from Karnataka.
If Mr Sircar, has switched from a 5 speed to a 4 speed in a similar car, its been a VERY BAD Short cut. The 5 speed had a different oil instead of the the normal high viscosity gear oil, and this may be the reason for the GB Packing up as service centres would have replaced the original oil with 90 Gear oil.

Whats the real Mileage this car has done?? Within 100000kms I guess.
