Parts for your 1998 Mitsubishi Lancer-Bump stops

1998 Mitsubishi Lancer bump-stops — what they do and when to replace them

Bump-stops are absolutely used and relevant on the 1998 Mitsubishi Lancer. The factory CK/CE-series workshop manual (1996–2000) lists a “jounce bumper” as part of the front shock/strut assembly, and the Mitsubishi ASA electronic parts catalogue shows bump-stop components for both the front and rear suspension. Major aftermarket catalogues for this model (including Monroe and KYB) also specify strut boot kits that include bump-stops, confirming they’re standard equipment.

On this Lancer, the front MacPherson struts use a foam jounce bumper hidden under the dust boot on the strut shaft. Its job is to provide a progressive cushion at full compression so the strut doesn’t hammer its internal stops. The rear suspension also uses bump-stops to prevent the arms and body from crashing together when loaded up over big bumps, potholes, or when the car’s carrying mates and gear.

Why they matter:

• Protects shocks/struts and top mounts from bottoming damage
• Helps keep tyres off guards under heavy compression
• Adds a progressive “last 10–15 mm” spring rate for control and comfort
• Cuts nasty thuds and improves stability on rough Aussie and Kiwi roads

Service advice for a 1998 Lancer: bump-stops are wear items made from micro-cellular polyurethane foam. With age, heat, and road grime, they harden, crack, or crumble—especially if the dust boot splits. They should be inspected whenever the wheels are off, and always when replacing shocks/struts or springs.

Tell-tale signs it’s time to replace:

• Perished, split or missing bump-stops under the dust boots
• Sharp thud on big bumps or when loaded, harsher ride than usual
• Uneven tyre wear from bottoming, or torn dust boots

Best practice when servicing:

• Replace bump-stops and dust boots as a pair with new struts/shocks
• Use OE-style foam bump-stops designed for this Lancer’s stroke—don’t trim them unless a matched lowering kit specifies it
• Ensure correct seating on the piston rod and that the boot positively locates on the stop
• Torque top-nuts to spec and get a wheel alignment after front strut work
• If the car is lowered, choose shorter, firmer stops matched to the reduced travel

A small part, but a big saver—fresh bump-stops help the Lancer ride nicer, protect pricey dampers, and keep handling tidy.

Does a 1998 Mitsubishi Lancer have bump-stops?

Yes. The OEM workshop manual for the CK/CE Lancer lists a jounce bumper in the front strut assembly, the Mitsubishi ASA parts catalogue includes bump-stops front and rear, and mainstream suspension catalogues offer dedicated bump-stop/boot kits for this model. They’re standard kit, not an optional extra.

How often should bump-stops be replaced?

There’s no fixed kilometre interval, but they should be inspected at every major service or tyre rotation and replaced whenever shocks/struts are changed. In Aussie and NZ conditions, many original stops are tired by 150,000–200,000 km. If the dust boot is torn, assume the stop needs doing as well.

What symptoms point to worn bump-stops on a 1998 Lancer?

Look for crumbling foam under the strut boot, harsh bottoming over speed bumps, a sharp “clack” when loaded with passengers or cargo, or tyres just kissing the inner guards on big hits. Any of those are a nudge to book a suspension check and likely refresh the stops and boots.
