I think I know the answer to this but I wasn't able to find a clear answer. I ordered bushing part no. LR018347 from AB a couple months ago which is listed as the only genuine front sway bar bushing for the LR3. I just installed them and the fit seemed a little loose, but tightened up ok once I torqued the bolts down. This made me question the part number and now I'm thinking LR015339 may actually be the correct part number and LR018347 actually fits the range rover sport that does not have stability control.

Is this correct? Looks like i need to order LR015339 and replace them. At least I figured out how to get them out without too much trouble. Thanks for the input.

 

All I can say is I installed 5339s on my LR3. Bought on eBay as LR4 bushings. AB shows LR018346 for LR4 though so maybe my seller was wrong for fitment. They were rather tight and slightly "squished" when the clamps went down. No problems in two years though.

Of note, stability control is the computer actuated sway bar I think.

 

LR015339 is the correct part number for the LR3 and they’re what I used. I assume the other part is probably for the RRS, which must have a different diameter sway bar.

 

I fitted LR015339 in Feb 2018, almost 40,000 miles driven since then, with no issues.

 

Thought I'd update this with a resolution. I ordered the LR015339 and that is certainly the correct part number. It fits as expected. LR018347 appears to be for a larger diameter sway bar and is not compatible.

 

RRS only, perhaps??? ...and places list it as fitting the LR3 as well, like so many other parts, but this one doesn't.

Just a theory. The RRS' suspension is stiffer afterall. Firmer control arm bushings we know...but maybe a larger swaybar, too...?
