Are all 940 prop shafts the same?

[martin calva]

The local garage showed me that there are strong vibrations when my car is on a lift with the engine running and in gear. The garage owner says the prop shaft, or possibly the differential, needs to be replaced.

My car is a diesel with an M90 gearbox. Not far from me someone is selling parts from a 940 with a petrol engine.

My question: Will any 940 prop shaft be suitable for my car, or must it be a prop shaft from a diesel 940?

To add to my post on your other thread you need to make sure the propshaft is from a diesel with the same gearbox as manual and automatic propshaft front halfs differ in length too

OK - the garage has told me that it must be a prop shaft for a diesel with my gearbox M90.

So please pay no attention to my query.

Many thanks for your two replies. I received incorrect information from a different source (not this forum) so I wanted to double check.

It could also be one of the plain bearings in one of the prop shaft universal joints. The "spiders" are still obtainable for quite reasonable prices. Next step would be to have the prop shaft rebalanced. I could have it done by a local truck modification shop, but it is not cheap.

Thank you for that info. I'm sort of flying in the dark here, trying to sort the problem out (in French) with the local garage, who are insistent that the best course is to replace the complete prop shaft but I am on my own in obtaining one, so I am very grateful for all help and advice here.

I have been offered a prop shaft from a 940 with an M90 gearbox but with a 2.3 petrol engine (mine is 2.4 diesel TIC). If the gearbox is M90, does it make any difference what engine is stuck on the front of the gearbox?

The B230 M90 is not like the the D24 one as the flange is not the same, dont know about the length

If you measure the length of the front section I might have something that matches

Many thanks for that helpful information. It has saved me for sending off for the wrong propshaft, losing money and taking yet more time to finally resolve the problem.

Being in France, I would try to find a replacement shaft in eg The Netherlands. You avoid any customs issues and there are still many 900s + parts around.

May I please ask you to double check that? The garage owner gave me the Volvo part number for the propshaft on my car (940 2.4 diesel with M90 box) as 9143070. Today I asked him to verify the part number and, after peering at various screens, he was adamant that it is the right part for my car.

This part number shows up several places as having been removed from a 930 with B230 engine, so either the garage owner is mistaken OR the same prop shaft will in fact fit both my 2.4 diesel and a 2.3 petrol 940.

I really want to be certain as I am desperate to get the car back on the road but, at the same time, I don't want to waste 384.34 € (quote from Sweden including shipping) and have another week without the car if it turns that it will not fit my car.
