Parts for your 1999 Toyota Hilux surf-Strut mounts

1999 Toyota Hilux Surf — Strut mounts: not applicable

For the 1999 Toyota Hilux Surf (N185 series), strut mounts aren’t used. Technical sources including Toyota’s N180-series Hilux Surf/4Runner Workshop Manual (Front Suspension section) and the Toyota Electronic Parts Catalogue for the 1999 N185 show a double-wishbone independent front suspension with a coil-over shock absorber, upper and lower control arms, and ball joints. There’s an upper shock support/insulator at the tower, but no MacPherson-style strut, no strut bearing, and no “strut top” assembly that handles steering rotation. Steering pivot is via the upper and lower ball joints, not through a strut top.

Why isn’t a strut mount used here? A strut mount is specific to MacPherson-strut front ends, where the strut acts as a structural member and the top mount contains a bearing so the whole assembly can turn with the steering. The Hilux Surf’s front end carries cornering and steering loads through the control arms and ball joints, so the shock’s top interface only needs a rubber insulator and hardware to locate and isolate the damper, not a bearing-type mount.

What should owners service instead of “strut mounts”? Focus on the parts this suspension actually relies on. The front shock upper insulator (sometimes called the top hat or support) can harden or crack and cause a light knock over sharp bumps. Front shocks themselves fatigue with age, and the coil springs can sag. Critically, the upper and lower ball joints, control arm bushes, and sway bar links/bushes are the key wear items affecting steering feel and tyre wear on this model. After front-end work, a wheel alignment is a smart move.

• Symptoms people often blame on “strut tops” are more likely from a tired upper shock insulator, worn sway bar links, or ball joints.
• When replacing front shocks, it’s good practice to fit new upper shock insulators and hardware at the same time.
• If there’s creaking on steering, look to ball joints and control arm bushes rather than any strut mount.

These conclusions are based on the Toyota workshop manual’s component breakdown and procedures for the N180/N185 front suspension, along with the Toyota EPC part listings that specify a shock absorber with an upper support/insulator, not a strut mount with bearing.

Popular questions

Does a 1999 Hilux Surf have strut mounts?
No. It uses a double-wishbone IFS with a coil-over shock and ball joints for steering articulation. There’s an upper shock support/insulator, but not a MacPherson-style strut mount or bearing.

What should be replaced when doing front shocks on a 1999 Hilux Surf?
Replace the upper shock insulator (top support), bushes, and mounting hardware with the new shocks. Inspect coil springs for sag, and check sway bar links/bushes and ball joints. Finish with an alignment.

I hear a clunk over bumps — is that a bad strut mount?
On this model it’s more likely a tired upper shock insulator, worn sway bar link, or play in a ball joint or control arm bush. A quick inspection will pinpoint the culprit before you start ordering parts you don’t need.
