Parts for your 2007 Nissan Maxima-Bump stops

2007 Nissan Maxima bump-stops: what they do and when to replace them

Technical sources confirm the 2007 Nissan Maxima is fitted with bump-stops (also called jounce or bound bumpers). The Nissan Factory Service Manual for the A34 Maxima lists a “bound bumper” within both the front MacPherson strut assembly (FSU section) and the rear suspension shock/coil assembly (RSU section). This is echoed by Nissan parts catalogues and major aftermarket suspension catalogues that supply front and rear jounce bumpers and boot kits for this model.

On this Maxima, the bump-stops act like a soft, secondary spring at the end of suspension travel. They’re there to cushion big hits, protect the shocks and struts from bottoming out, and keep the suspension geometry behaving when the car is fully loaded or hits a sharp bump. Without them, the strut can slam metal-to-metal, which feels harsh, can knock, and may damage internal valving or top mounts.

As part of routine servicing on a 2007 Maxima, it’s smart to inspect the bump-stops anytime the tyres, brakes, or suspension are off, and definitely whenever shocks or struts are replaced. They live under the dust boots, so a quick look for crumbling foam, splits, missing chunks, or perished rubber is worthwhile. If the dust boot is torn, grit and UV will chew through the bumper in short order, so replace the boot and bumper together.

Replacement is straightforward for a workshop but usually involves removing and disassembling the strut, so a spring compressor and proper safety gear are a must. Most techs will fit new bump-stops and boots as a kit with fresh struts or shocks. Replace them in pairs (front pair or rear pair) to keep the car’s response even left-to-right. After front strut work, a wheel alignment is recommended to keep steering feel tidy and tyre wear even.

For drivers running standard ride height, quality OE-style foam or microcellular polyurethane bump-stops are ideal. If the Maxima is lowered, consider shorter, progressive-rate bump-stops designed for reduced travel, trimming generic stops isn’t advised unless the manufacturer specifically allows it. Beyond periodic checks, bump-stops are low-maintenance—avoid petroleum-based cleaners, keep boots intact, and they’ll quietly protect the suspension for years.

FAQs

Does a 2007 Nissan Maxima have bump-stops, and where are they?
Yes. They’re integrated into the suspension as “bound bumpers”: up front inside the MacPherson strut under the dust boot, and at the rear on the shock/coil assembly. They act as a last line of defence when the suspension nears full compression.

How often should bump-stops be replaced on a 2007 Maxima?
There’s no fixed kilometre interval, but they should be inspected at every major service and replaced whenever struts or shocks are renewed, or if they’re cracked, missing pieces, or the boots are torn. Many technicians treat them as a “while you’re there” item during suspension work.

Is it OK to drive with damaged or missing bump-stops?
It’ll drive, but it’s not ideal. You’ll feel harsher thumps on big hits, may hear knocking, and risk damaging shocks, top mounts, or even bending components over time. Replacing them restores proper ride and protects the rest of the suspension.
