Pinpoint the source of a suspension knock
Drop links connect the anti-roll bar to the suspension. Wear can cause rattles or knocks, but similar noises need to be ruled out.
Joint play
Drop-link ball joints and boots are checked for movement, damage and loss of grease.
Anti-roll-bar bushes
Bush movement and bar location are considered because worn bushes can sound similar.
Other suspension joints
Top mounts, ball joints, track-rod ends and accessible arm bushes are checked for related play.
Side-to-side condition
Both sides are assessed; replacement recommendations are based on condition and manufacturer guidance.
How the SP88 visit works
1. Vehicle details
Send the registration and describe when and where the knock occurs.
2. Evidence-led checks
SP88 inspects the suspension safely and identifies the component with measurable play.
3. Clear repair route
Suitable links and fixings are fitted, torqued and road-checked where safe.
Many drop-link jobs can be mobile
Where the vehicle can be lifted securely and fasteners are serviceable, replacement may be completed at the vehicle. Seized fixings, corrosion or additional suspension damage can require workshop equipment.
Safety: Stop and arrange inspection if the vehicle feels unstable, steering changes suddenly, a wheel sits abnormally or there is severe metal-to-metal noise.
A small part still needs a proper diagnosis
SP88 does not replace drop links solely because a car knocks. The correct side, link design, fixings and surrounding joints are checked so the repair addresses the measured fault.

Questions customers ask
Do drop links have to be replaced in pairs?
Not automatically. Condition, vehicle guidance and access determine the recommendation; both sides are checked.
Will new drop links cure every front-end knock?
No. Bushes, top mounts, joints, brakes and loose components can create similar noises.
Is wheel alignment needed after drop-link replacement?
Drop-link replacement alone usually does not set wheel geometry, but any additional steering or suspension work may change the requirement.
