Yes it can be with a little effort working on the LR but worth it in my book.
My 95 D1 w/ 5 spd and 4.6 suspension is at 142,560 miles with original lifetime non greaseable ball and tie rod joints maintaining almost like new joint tightness and stiffness.
Only item I replaced was the rubber rear flex joint as I had vibration problems destroying that POS rubber flex joint with a driveshaft having a real steel U joint off a Range Rover. A Christmas sale item from Rover's North or Atlantic British????
I drilled, tapped and installed zerks on every joint on the D1 including the anti-roll bar link ends and A arm locating the rear diff.
Lifetime joints do not have a ground in grease groove in the ball allowing grease to pass by the seated ball passing to the rubber grease sacks.
Greaseable replacement joints have a grease groove ground into the ball.
I modified a four finger welders Vise Grips bending the fingers a little allowing the Vice Grips to compress tie rods and ball joints enough to unseat the ball allowing grease to pass by the ball refilling the rubber grease sacks.
Driveshaft U joints and slip splines lubed at every oil change around 34 to 3,500 miles. Engine holds 8 qts 11 ounces including the pre-oiler and 7" long Hastings PH426 oil filter which holds over a qt itself. Cleaned, inspected then repacked wheel bearings plus checked and corrected for steering ball pivot preload as well steering box. Installed Poly suspension bushings first month of ownership. Drag link or Pitman arm removed to properly adjust or preload the steering box.
The steering box, Rover purchased and had the rights to manufacture that POS Ford used for only 17 months until Ford production switched over to the Saginaw box. Way cheaper and common for several years. I know as my 68 F250 Pick Up of 69K original miles had one of those POS leaking boxes leaking before 50K miles. Twitchy at speed another bad feature plus seal kits became NLA and before at $153 each kit. A small step up from manual steering but a POS until I installed a Saginaw box in my Pick Up. BTW ordering steering box rebuild kit, starter (Nipon the best i've found) plus alternator brushes and small parts kits from England vs unit replacement only big $$$$ by LR dealerships in America. Spare distributor (95 last year having a dizzy a 7,800 mile donor) alternator and starter all stored in the back of the D1.
This is how I keep my LR running not dealing with expensive dealership repair bills besides all they work on is new to 5 years old, i'm a 95 D1, older than some of the mechanics, oops I mean "techs". ....~~=o&o>.....
