I am just starting to strip and rebuild the gearbox on my freelander. Does anybody no what is actual inside the final drive carrier as shown below. If I was to open it up what would I find in there? Thanks

Thanks but why post such a useless thread, this is the Freelander section so why post if its completely off topic! Are all 38a owners nobheads then :confused:
 
No, the planetary gears are in the IRD unit which connects to this output shaft. The hole in the middle is where the front on-side drive shaft passes through from the IRD. Weird way of doing it but it saved space I guess.

I don't know the answer to your question Tank, but I would guess that a main support bearing would be the most likely candidate.
 
If, by diff carrier, you mean the IRD then the answer is yes it can cause vibration if it is knackered. It is a well known failure on the Freelander and a quick search on here for IRD will reveal all. I hope you haven't stripped your gearbox for nothing as the IRD is a separate assembly.
 
No I meant whats inside the actual diff itself. Thankfully I no the IRD isnt causing the vibration because it was changed recently along with the viscous coupling:)

What would happen if I fitted a box with a very slightly higher final drive ratio, presume it would still drive ok which is the main thing?

Make sure you only buy a Freelander PG1 as the other types (Rover cars) will not fit your IRD input spline.

A diesel unit would work on a petrol vehicle and vice versa.
