Parts for your 1997 Nissan Navara-Bump stops

1997 Nissan Navara Bump Stops

Yes, bump stops are fitted to the 1997 Nissan Navara. Technical sources that identify them include the Nissan D22 Navara/Frontier Factory Service Manual (FA: Front Axle & Suspension and RA: Rear Axle & Suspension), which shows front “bound bumpers” on the control arms and frame-mounted rear bump stops for the leaf-spring axle. The Nissan FAST parts catalogue also lists front and rear bump stop part numbers for D22 (1997-on), and common parts catalogues from brands like Nolathane and SuperPro supply direct-fit replacements for this model year.

On a ’97 Navara, bump stops do a simple but crucial job. Up front, with the torsion-bar independent front suspension, they limit suspension compression, protect the shocks and control arms, and stop metal-on-metal contact when the ute bottoms out. Down the back, the frame-mounted stops prevent the live axle and leaf packs from over-travelling under heavy loads, towing, or when bouncing through ruts off-road. They also help manage ride quality by softening the last bit of suspension travel.

As part of routine servicing, it’s worth giving the bump stops a look. Rubber hardens and cracks with age, oil, and UV, and once a stop perishes or drops off, the next big hit can feel harsh and can stress other components. Many owners find that by 150–200,000 km, original stops are tired, especially on vehicles that carry loads or see a lot of corrugations.

• Check for cracks, missing chunks, or a flattened, shiny contact face.
• Look for metal-to-metal witness marks that suggest you’re riding the stops.
• After any torsion-bar adjustment or lift/levelling, confirm clearance to the front stops at normal ride height.

Replacement is straightforward: safely support the vehicle, unbolt the old stop, clean the seat, and refit a like-for-like unit. OEM-style rubber keeps the factory feel, polyurethane options are tougher and resist oil, but can feel a touch firmer on sharp bumps. If you’re regularly on the stops when loaded, consider better-rated shocks or helper springs rather than relying on the bump stops to carry the weight.

Torque specs and clearances vary, so use the Nissan service manual for your exact setup. A fresh pair of stops is cheap insurance for the rest of the suspension, and keeps the Nav ticking along happily on rough Kiwi and Aussie roads.

FAQs

How do you know the bump stops on a 1997 Navara need replacing?

Tell-tales include visible cracking, chunks missing, or a glossy, squashed contact face. If you’re feeling harsh bottom-outs or hearing a clunk over speed humps or when loaded, the stops may be perished or you’re regularly hitting them.

Also check after any ride-height change. If there’s minimal clearance at rest, you’ll be on the stops more often, which accelerates wear and makes the ride crashy.

Should you upgrade to polyurethane bump stops?

Polyurethane is tougher and oil-resistant, great for heavy use and gravel work. It can transmit a tad more sharpness than rubber, so daily drivers chasing maximum comfort often stick with OEM-style rubber. For utes that tow, tour, or see off-road loads, poly can be a good, long-life option.

Do torsion-bar adjustments affect the front bump stops?

Yes. Winding torsion bars up or down changes ride height and the gap to the front stops. After any adjustment, confirm there’s adequate clearance at kerb weight and that the upper control arm isn’t sitting on the stop. If it is, correct the height or consider complementary suspension changes.
