After a broke connection I fitted a brand new prop shaft. (well, I drove about 600 km with no prop shaft) Now a couples of weeks after fitting the new prop shaft I just realised that some sort of light oil has been running out from the park brake drum.
Can anyone give me a hint of where this oil is coming from or more importantly where is this oil missing? On the picture it is possible to sea a droplet hanging on the drum.  Click image to enlarge Any hints would be highly appreciated. Thank you very much in anticipation.  |

Probably the transfer box rear output seal.

Rear output seal, i had to do mine twice before it stopped leaking. I just cleaned the brake shoes (brake cleaner) incase it leaked again and there still working like new. I'll keep the new set as spares.

There was a recall on early Pumas for this problem.
The engine and gearbox on the Puma are tilted backwards more than any previous LR engine and transmission with the result that the oil level is higher at the back of the transfer box than in the past. The original seal was inadequate and a replacement seal was retrofitted in early vehicles. Has yours had this done? |

Cheers for the comments – a bit worrying though.
The car is new to me and I don't know the history  (2008)
The only thing I know is that the previous owner (some sort of Spanish construction company) has hated the car with passion - judged on the way they have treaded the car. Can anyone give me a hint of the skills required (on a scale from 1 to 5) for how difficult it is to sort this out by myself (I am not particular skilled when it comes to car mechanics) |

I would say a bit more complicated than removing a wheel. Have a look into the shop manual and you´ll figure out. I vote "2". Puma 110" SW

Not difficult to replace the seal, if that is the problem (which is 98% certain). On the 1 to 5 scale I'd put it at 2.
1) Chock vehicle in both directions 2) Disconnect front end of rear propshaft, tie propshaft up out of the way 3) Slacken handbrake adjuster and remove handbrake drum 4) Remove centre bolt or nut from output flange and pull off flange 5) Lever out old seal. 6) Fit new seal (using something like a large socket to tap it into place evenly) 7) Refit flange, torque retaining bolt or nut to correct figure  Refit handbrake drum and adjust handbrake
9) Refit propshaft Note that the handbrake shoes may well be contaminated with oil and therefore need replacing, also that there is a risk (if they are still clean) that oil will run out once you take the output flange off. For this reason you might want to remove the old shoes before step 4 above. The whole job shouldn't take more than an hour (probably half an hour if you have a decent workshop) but if it is your first attempt I would allow three. |

Cheers guys
I can easily do that! 
Now I just need to identify the order-numbers for the seal and brake shoes and find out who can deliver it to France. I guess I need to re-fill the oil as well.
Thank you so much! |

Part number for the seal is FTC4939 £12.94 (this is from last months microcat.... I'd have thought it would have changed if it was upgraded, unless they (LR) just changed the design of it and kept the part number the same)
Handbrake shoes are ICW500010 for the "kit" (i'm assuming theis includes 2 shoes and new springs) £78.53 |
