I'm suprised the bushes had failed in only 30k miles. Have you been using a LR specialist for the work? On my old L320 they lasted 12 years and 70k.

Thank you for your message, all your points are valid. I only take the car to main dealer (Harwoods in Brighton since owning it when it was 1 year old). The only thing I do outside is the tyres as they’re much cheaper elsewhere. I use a formula 1 Autocentres which are very good I use them for all my other cars. So there’s a level of trust. And I’ve used them for the tracking.

From reading on here and the D3/4 site, the car should be on level ground before adjusting the ride height and then tightening the adjutment bolts. If they're torqued up while the wheels are off the ground, the bushes will twist when it's lowered and prematurely fail. There are measurements to ensure it's the correct height (again from memory from the centre of the wheel to the wheelarch).

Looking at the parts catalogue there are several part numbers for the l/H and r/h lower arms, but for a 2018 SVR you have the correct items, they are classed as Premium Front Spring Bushings as opposed to standard on all other vehicles. As long as the suspension was at the correct height (471mm from centre of hub to underside of wheel arch) before being torqued up then there is no reason the bush should have failed through twisting. Have you checked you don't have a binding front caliper causing the pull to one side? |

Were the retaining bolts tightened when the weight of the car was on the wheels. Otherwise, the bushes would be in a constant state of tension, resulting in shorter life. |
