South African roads are hard on suspension. Potholes, speed bumps, gravel access roads and heavily loaded bakkies mean this category sees more genuine wear than almost any other, which changes the maths on what's worth buying used and what isn't.
Buy used, or buy new aftermarket? Be honest about it
Some suspension parts make sense used; some don't. Shock absorbers and coil springs are pure wear items: a used shock has an unknown fraction of its life left, and decent new aftermarket shocks for a Polo or Corolla cost little more than used ones. The same goes for bushes, ball joints and tie-rod ends: cheap enough new that buying them used rarely pays. Where the used market genuinely earns its keep is on the expensive assemblies, such as steering racks, power steering pumps, complete knuckles and hubs, control arms, subframes, and bakkie leaf-spring packs. Those are the parts where new prices hurt and a good used unit saves real money. We'll tell you the same thing if you request a part that's cheaper bought new.
What's actually available
Steering racks and pumps for Hilux, Ranger, Quantum, Polo and Corolla are steady stock. Complete front struts, control arms and knuckles are usually pulled as assemblies. Leaf springs and rear axle parts for Hilux, Isuzu and NP200 come up often because work bakkies get overloaded and sagged springs are common.
What it costs
A hydraulic steering rack typically runs R1,500 to R5,000 used; electric power steering (EPS) racks go higher, R4,000 to R10,000, against new prices that can pass R25,000. Power steering pumps run R800 to R2,500. A complete control arm with ball joint is roughly R400 to R1,500, a knuckle with hub R800 to R2,500, and a leaf-spring pack R1,500 to R4,000 a side.
What to check before you buy
- **On a steering rack, pull back the rubber boots at each end.** Fluid inside the boot means the rack seals have gone, which is the exact failure you're trying to replace. Then turn the input shaft lock to lock by hand: it should be smooth with no notchy spots or dead play in the middle. - **EPS racks can need coding.** On many newer cars the electric rack talks to the body computer and may need calibration or coding after fitment. Confirm with your fitment workshop before buying, and match the part number exactly. - **On control arms and knuckles, grab the ball joint and check for play**, and look at the bushes for cracking or oil contamination. A control arm with dead bushes isn't a bargain: pressing new bushes in costs labour. - **On pumps, check the pulley for wobble and the shaft seal for weeping.** Ask if the donor car's steering was whining. A pump that ran low on fluid is on borrowed time. - **On leaf springs, count the leaves and compare the arch side by side** if you can. A spring off another overloaded work bakkie may be as flat as the one you're replacing. Look for cracked leaves and worn-through anti-friction pads. - **Match drivetrain and spec, not just model.** A 4x4 Hilux knuckle is not a 4x2 part, and a bakkie with a factory tow or load package may carry different spring rates.
