pretty sure both of my rear uppers were factory and died around 135k miles. My front lowers were date stamped 2006 so they were probably original to.

 

I put that complete set on my 2007 HSE. It was much firmer and rode like my old SCCA Mustang. Very FIRM., very TIGHT. Every bounce or pot hole was felt. It might be good for a weekend toy, but I hated it as a daily driver. In fact I hated it so much that after the first month, I bought a complete set of genuine Land Rover Arms to replace them, but the car was flooded by Hurricane Harvey before I had a chance to put them on.

That being said, the current 2007 SE needed new bushings on the front lower control arms. (I have plans to put the new arms still sitting on my shelf on my 2006 SE)
So I put OEM bushings on the lower front and the Orange Polybush on the lower rear (and new bushings on the sway bar while I was there).

Still has the Land Rover ride I like and the comfort of knowing I will not be back in here in the next 50K-60K miles to replace the rear bushing again.

I may be inclined to try Polybush on both lowers on the front, but nothing else on a daily driver.

Just my thoughts on the issue.

I think you replaced the most critical one, Jeff. The front lower rear is the hydro-bush and the one that typically fails ever 50k'ish.

 

Yeah, I have heard that, but so far I have 60k since I have owned it and the front lower rear is still OK as far as I can tell. I don't know if or when they were changed before it hit 70k when I bought it. I will give them another good look over before I take this thing in for an alignment. Last arm and bushings are out. Just need to sand blast, paint and reinstall now.

Oh and extract that damn little bolt that broke off in the center bottom of the air compressor housing/bracket.

The one I had big trouble with is the rear upper rear - both the bushing and outer sleeve were totally shot - came out in pieces when I finally got the bolt out - both sides.

 

I guess my take away is:

Polybush on the BIG bushings and OEM or on everything else.
Regardless of where it is.

I see your line of thinking, but I would add the rear upper rear as well. It's not a big hollow one like the others that look a bit under designed for the weight, but I certainly would not put back in the tapered rubber and aluminum/magnesium thing that was in there. Based on looking at all 12 of my rear bushings, those were by far the first OEM to go bad. Plus they can ruin the tires, and these tires aren't cheap.

Edit: I have revisited my thinking here - see my post #45 - 3/12-19

 

Do you mean the rear upper inners or outer bushing?

 

I'm talking about the rear wheels, upper control arm, rear bushing, inner, at the body, not at the knuckle.

 

For me I thought he one at the knuckle was undersized, cut compared to the lowers they are all small

 

Yes, the ones at the knuckle are small. But they are a different kind of bushing than the others. They are just there for toe movement as far as I can tell. I replaced mine, but probably wasted my money. They were tight and looked to be in excellent shape. I guess I'm hoping I don't have to go back into the rear suspension for a long time.
