Isn't that a diesel? We don't have them here in the US. Mobil 1 0w40 is fantastic oil but it is not diesel rated as far as I know. IMO you need to stick with diesel oil. There are some Jeep guys from the UK on here hopefully they will chime in.

K&N air filters let a lot of contamination in, not a good idea for a diesel either IMO they run dirty enough as it is. Actually the Mopar air filter is great if you can find it, otherwise a good aftermarket would be a better choice.

Paper air filter...does not seem to matter which in my experience! I use the paper ones with the layer of foam for a bit of extra life to the the filter. Any fully synth oil of the right grade....whatever I can get a deal on but not shops home brew!

Just rebuild the calipers. Just did all four of mine...dead easy. Took about 1/2 an hour per corner. My seals were good...reused them... but the bores had a layer of build up stopping the piston sliding easily. No cost except your time and 1/2 a litre of brake fluid or so.

nice 1 alfa i get ver good discount on mobil 1 so will go with the Mobil 1™ Turbo Diesel 0W-40 also gona drop the gearbox sump and change fluid n filter thought it may be a good idea to do the diffs as well cant see a drain bung so i imagine its seringe it out and fill till it trickles out and i also see a mention of friction modifier how do i know which one is correct for the 2.7crd ?... ok hear is a newby question acording to data i also have a transfer case not sure where this is ? imagine its after the gearbox.. i whish there was a paper manuel for the 2.7 crd... so much to learn... ps thax for the advice about moding the bulk head has made doing the injectors a breaze... thnx again..

Ok . You can syringe the oil out of the difs but you won't get any metal particles out that way or be able to check its condition. Take the covers off clean it out and rtv the covers back on. Use quality dif oil.
If near your gear selector levers it says QuadradrIve (unlikely) then that what you have and you need friction modifier in the axles only. If it says Quadratrac (most likely) then you don't need fm. Either way the transfer case is the same one and needs the factory spec fluid ONLY...mopar if you can find it (discontinued in the UK) Petronas other wise.
You are correct about the tc location.
If you hunt back to one of my early threads you will find a link to pdf versions of the CRD parts manual and factory service manual. Download it and just print pages as you need them. Would put link on here but can't do it on my phone. Cheers!



EDIT; Found the Parts and service manual link:
