2007 Nissan Primera Exhaust Mount — What It Does and When to Replace It

The 2007 Nissan Primera (P12) absolutely uses exhaust mounts (also called exhaust hangers or rubber insulators). This is confirmed by the Nissan Primera P12 Factory Service Manual in the EX (Exhaust System) section, which illustrates the exhaust supported by multiple rubber mounting insulators, and by the Nissan Electronic Parts Catalogue (EPC) entries for the P12 showing rear and centre hangers. Major aftermarket catalogues from brands such as Bosal and Walker also list specific mounting rubbers for the 2002–2007 Primera range, so the part is very much relevant to this model year.

On the Primera, exhaust mounts are the small, tough rubber pieces that suspend the exhaust from the body. Their job is to hold the exhaust at the right height and alignment while isolating vibration and movement. That keeps rattles down, protects the catalytic converter and flex joint from stress, and stops the muffler or tailpipe from knocking the bumper or rear beam. They’re simple, cheap, and crucial for keeping the exhaust where it should be.

Because they’re rubber, they harden, crack, or stretch with age, heat, and road grime. On a 2007 car, many original mounts are well past their best. During routine servicing, it’s smart to inspect every hanger from the front pipe to the rear muffler. If there’s any tearing, elongation of the holes, shiny witness marks on nearby metal, or the exhaust looks low or off-centre, it’s time for replacement. Swapping them is straightforward: support the exhaust with a jack and a block of wood, spray the pegs with silicone spray, and lever the old insulators off. Fit quality OEM-equivalent rubbers and replace in pairs on the same section to keep the system sitting square.

• Common symptoms: thuds over bumps, a tinny rattle at idle, exhaust tapping the subframe, or a droopy tailpipe.
• Service tip: inspect mounts every 10,000–15,000 km or at each oil change, especially if the car sees rough roads or short trips.
• While you’re there: check the flex pipe, heat shields, and rear muffler seam for cracks—mount wear often masks other issues.
• Don’t ignore a broken mount: extra movement can stress welds and flanges, leading to leaks and pricier repairs.

FAQs

How often should exhaust mounts be replaced on a 2007 Nissan Primera?
They don’t have a fixed interval, but by this age many originals are due. A good rule is to inspect them at every service and expect replacement roughly every 60,000–100,000 km, sooner if the car lives in hot climates or does lots of short trips. If there’s visible cracking or the exhaust sits low, replace them straight away.

What are the tell-tale signs of a failing exhaust mount?
Listen for dull knocks over bumps, buzzing or rattling at idle, or clunks when taking off. Look for a tailpipe that’s off-centre in the bumper cut-out, shiny rub marks on the subframe or heat shields, or stretched/cracked rubber insulators. Any of these point to a mount that’s on the way out.

Can a home mechanic replace the exhaust mounts?
Yes, it’s a straightforward DIY for someone handy. Safely raise and support the car, support the exhaust, use silicone spray or penetrating oil on the hanger pegs, then lever the old rubbers off and slip new ones on. If bolts or brackets are heavily corroded, or the exhaust needs re-alignment, a workshop visit is a safer bet.
