Transmission Hole?
Removed the rear wheels and wonder what is this hole (green)? Should there be anything to cover it? and what is the plastic thing (red) at the tranny?
 Also, my right and left rear wheel hubs have different nuts.   Which one is original? Red or green? Should I change another one to original? Or I shouldn't be worry about it? Thank you! |

Frankly my dear....

Hi there, the PET shows a rubber cap should be fitted in the housing hole, I just checked mine and one is fitted. However, although the PET shows the part and gives it a number (49) they do not give a part number! Really useful...but you could just get a big rubber grommet.
The thing you circled in red is the electronic speedo sender unit. So, I am guessing that you have an early 944 or a 924S car and at some point a later transmission has been fitted - the early cars do not need the sender as the speedo is cable driven. The OEM locknut is the red one, the castellated nut (green) looks like it has been fitted after someone replace the wheel bearing on that side. I cant recall ever seeing a hole drilled through the hub threads...but you never know...! I wouldn't worry too much about it though...

Interesting.
The green hole is supposed to have a plastic plug in it- though I have never personally see one. PET doesn't list a part number. Not to worry, it's just an access hole and doesn't seal anything. The sensor circled in red is the engine speed sensor. If there is no wires going to it and your speedometer works, then you can bet that the PO replaced the transaxle as I believe earlier cars have the speedo sensor in the wheel itself. If there are no wires going to it and it DOESNT work, then now you know why. You have two different stub axles, meaning the section of axle between the CV joint and the hub. The later cars use the type in the first picture IIRC. The castle nut has the cotter pin to prevent it from backing out- the other has a nut that is sort of "egg'd" on the end and stretches as you install it, so it's one time use only. There is nothing wrong with either, I suppose. |
