Had my Td5 for about a month now. Just had front wheel bearing done (MOT advisory) plus A frame bushes (hopefully to cure knocking sound when changing gear - not got car back yet so I suspect it has softened the knocking rather than fully cured it and expecting half shafts to need doing too) .
I had these done at a local LR specialist and asked them to give me a heads up on any other issues they spotted. Good news is nothing else of note and they reported it to to be very solid underneath - they even said don't bother doing the track rod end (another MOT advisory) as there was hardly any play.

My plan is to keep the car a few years so i want to to lightly renovate over this year. I have not done much like this in the past so will tackle easier jobs myself and send to garage for anything more troublesome (unless i get confident).
Have new socket set, Haynes manual and youtube - how hard can it be !
Ordered full service kit plus all new oils for engine, gearbox, transfer box and diffs and plan to do this over the next 2-3 weekends plus a cooling system flush.

I would appreciate any thoughts / guidance on a list of things to look at / replace over the year (using standard parts in the main).
Car is 16 yrs old and mileage is quite high at 180k but its been pretty well looked after .

My current list (assuming these parts are largely still original on the car so probably well worn by now):
replace all shocks and springs
Replace all suspension bushes
Replace all brake hoses (and check brake pads / disks)
Replace all engine flexible hoses
track rod ends

is there anything to consider on engine / gearbox etc due to the high mileage (garage didnt mention anything)

all thoughts / ideas much appreciated.

Change all oils and lubricate/grease every other moving part, including all UJ's + change swivel joint grease with one shot. Change coolant and give system a thorough reverse flush with heater fully open + it's really worth taking a close look at the electrical wiring to make sure it's not going to turn itself into a three bar electric heater

As V8250 said.
Definitely check your UJ’s though for any movement if you can here knocking.

Change all fluids, but dont replace anything mechanical unless it is either worn out or close to the end of its life.

Iirc td5 oil spinner filter needs a special spanner?

search for lt230 spline wear

And fit lots of security as well
