Clunking persists after new bushings

[rally3]

Land Rover warranty will only pay the dealer to replace the bushings, not the whole arm

Part number shown (LR073366) is for the rear bushing of the front control arms, which AFAIK is the one which usually wears prematurely and causes clunking.

Ah blast, never mind. Got confused.

Wonder why that is? Believe the arm itself could not break within warranty period?

Everything comes down to cost
The bushings cost about 70-80 each, and they only pay maybe 1 hour beyond R&R of the arm, vs the $400 plus each arm costs (at dealer pricing)

Yeah, if JLR is paying, they'll want to pinch pennies, so you only get a new bushing. If you are paying, replacing the entire control arm makes more sense IMO - especially if the odo is on the high side, say 100kmi+. New ball joints are always a good idea with high miles, and complete OE/Genuine control arms are $250-$275 each from discount dealers with new ball joints & bushings... about the same labor either way.

(Yes, I know aftermarket LCA's are available for half that, but I've yet to see OEM units in that price range... and I've had bad experiences with Meyle and other off-brand parts.)

Almost certainly the swaybar bushings by your description. I'm surprised your dealer couldn't figure that out. I'd have them change those, and then maybe shop for a new mechanic (or dealership since you are under warranty).

The "transverse" part is the giveaway that it's the swaybar bushings and not the LCA bushings. If you want to test the LCA bushings yourself, idle along (like in a parking lot) and then briskly hit the brake pedal. You'll hear a "clunk" if the LCA bushings are shot. The swaybar bushings make a distinctly different sound (deeper in tone) and happen when weight is shifted from side-to-side.

Thank you. Will relay and revert.

we have a 2015 Land Rover lr4 that has made a persistent clunking when traversing ramps or curbs at an angle. For example, if you pull out of our driveway that has about a six inch ramp drop to street, there is a clunk that seems to come from front. Dealer replaced front bushings under warranty, saying they had separated. LCA fine, as were tie rods.

We also own a 2016 LR4 and have owned two more prior - unique sound.

Any ideas?

They should have replaced the control arm assemblies. The new bushings rarely fit as tight as the originals due to the composition of the control arms.

Mystery solved...loose radiator core support. Bolts tightened and knock is gone.
