You're in a tough spot. I think your estimate is about right.

Some folks pic on my old LR3 but $5k and having another 60k miles with no car payments may be worth it

Hey the part with spring we can't figure what it is, just might be from my 2011 LR2 transmission... I put my foot on the brake and feel movement on the shifting ****. Dakota thought it may be transmission and just might be

The people who pick.on your LR3 are simply unaware of its prowess and character. Don't let them borrow your keys for two weeks or you won't get them back.

Most cars with a shift lockout have a solenoid in the shift lever that engages when you press on the brake to allow you to shift out of park. If I’m in Park and press on the brake while resting my hand on the gear selector, I can feel the solenoid trip in the shift lever in my wife’s XC90. I didn’t notice this for almost 2 years so I thought something was wrong the first time I noticed it.

The fill plug is #30 in the diagram Dakota posted, and is on the rear of the differential. I believe the mystery loose parts are a broken #8 which is listed as the "damper" and is installed on the front (drive shaft side) of the differential. The hole you pictured is very close up, so orientation on the diff is hard to determine, but this hole is on the drive shaft side, correct? It looks to me like the damper broke off and left its innards in your driveway and a large hole in the front of the diff. If you look at Dakota's awesome cutaway pic, the tip of the damper looks like your mystery part.

That part... I am not certain its from the rear diff. Looks more transmission related. Here are some pics, my only guess is that maybe that pin/spring could ride inside the damper on the rear diff, but that is never removed and I don't see how the part could come out unless there is some catastrophic internal damage to the diff. And even then the odds of it getting out of the fill plug would be insane.




This is part of the clutch engagement control. I cannot remember what the name of it is right now, but I do not believe it is the fill/drain plug. It would explain the spring and plunger you found on the ground, Looks like the plunger cap just broke off and let the insides fall out.

That is called a damper, per the workshop manual. How it works, no clue.

P-Bod, I am looking at photos of used locking diff and I think you are right and I think our original thoughts of it being the fill plug are indeed wrong. Here is another epic for compassions, not the actions work is dead inline with were the damper is located.... So yeah, that explains the weird o-ring and everything that looked "wrong" for it being a fill plug location, cause its not.... Reason #200 why good pics go a long way.

So how the heck does a damper break off like that? And I wonder if a new one can simply be installed or is there some damage, alignment that must be done?

You guys nailed it. Found pics from rear diff when bought at 90k miles and took pic today. Clearly the plunger!
In 2019 Dakota noted the contamination on the diff... I got it clean and saw some leakage where e-motor mount to diff. I would wash under Under entire LR3 ever few weeks and never saw dripping on driveway. Did make some post about some clanking noise in diff and and it really did not seem to lock when it should have at rear. Seems diff is likely shot. Having towed to shop next week. Thinking front and rear diff need a rebuild as front has a some howling. Dont know cost of diff rebuilds but plan on having it done.

Pics attached
