How many miles are on your LR3
The same thought occurred to me - if front venting is a problem, then the rear probably is a well.
The reality is I could not find anything anywhere to suggest the rear vent that runs up along the fuel filler hoses is any sort of problem.
I guess the real question is does the LR4 use a different vent for the rear than the LR3; that was how I tweaked to the potential problem re the front - from reading about blown seals and there being suggestions that the problem was a plugged differential vent rather than some seal problem.
Regarding the rear, I have not read so much about there being a leaking seal problem with the rear. This front vent problem and solution is typical of all the vehicle manufacturers - they are aware of a problem and often resolve the problem for future production, but as to existing vehicles, let bygones by bygone.
This was about all I have found regarding the rear differential vent.
The cast iron casing comprises two parts; a cover and a carrier. The carrier provides locations for all the internal components. The carrier is sealed to the cover via an O-ring seal and secured with twelve bolts. The cover and carrier have cast fins, which assist mobility. A breather tube is fitted to the top of the carrier. This allows a plastic tube to be fitted and routed to a high point under the vehicle body, preventing the ingress of water when the vehicle is wading.
A smaller pipe, which is not associated with the fuel system, is attached to the side of the fuel filler pipe. This pipe connects to the rear differential and provides breathing for the differential case. The pipe terminates near the fuel filler head.

I have nearly 170,000 on my 2007 HSE. I'm starting to get a little leary about it and will probably not take it on any extended trips. Other than that, it's been the best vehicle I've ever owned!
My 2007 SE V8 is coming up on 180K. Last summer I had a bunch of work done to keep it rolling. Coil Conversion, heater core needed to be fixed, transmission service, tie rods , toe links plus some other routine maintenance like brakes etc. Pretty big bill for sure but as my mechanic said - you know this car...try and find another one and you may end up with more problems than yiuy already have. Glad I got it done. Of course I know wit won't be the last of the work it'll need, but it's a great car and should last me a long time.
2008 LR3 here, about 153k on it. After I finish a customer project I'm going to be doing a refresh of the cooling system and pulleys/belts, and doing all the control arms and steering components to tighten it all up and deal with some thunks.
Ive had my 2006 LR3 for about five years. I purchased with 150k miles and it's currently sitting at 285k miles. Lots of long road trips and driving on trails around the western US. I've been very curious to find out what the upper limit is for these. With regular maintenance and upkeep, it's still running strong.
