1987 Suzuki Jimny Exhaust Mount — What It Does and How to Look After It

Yes, an exhaust-mount is absolutely used on a 1987 Suzuki Jimny. Factory documentation for the SJ410/SJ413 era (which covers 1987) shows rubber exhaust hangers/insulators supporting the system from the chassis. Suzuki’s service manuals and the Suzuki Electronic Parts Catalogue list muffler hangers and rubber insulators for the mid-pipe and rear section, and independent workshop guides for SJ410/SJ413 likewise illustrate the exhaust suspended on rubber mounts. So, the part is relevant and fitted from the factory.

On this tough little 4x4, the exhaust-mount’s job is simple but critical. The rubber hangers isolate vibration, stop the pipework drumming through the cabin, and keep the exhaust aligned so it doesn’t stress the manifold or knock on the chassis, axle, or body. Off-road flex and corrugations can be brutal, and these mounts take the brunt so the rest of the system doesn’t crack or loosen.

As part of routine servicing on a 1987 Jimny, it’s smart to eyeball the mounts whenever it’s on stands or a hoist—say every 10,000 km, or after beach runs, river crossings, and rocky tracks. Look for perished rubber, splits, elongation of the holes, obvious sagging, or any contact marks on the pipe or body.

• Common symptoms of tired mounts: exhaust thuds over bumps, rattles at idle, visible droop at the tailpipe, or a harsh vibration that wasn’t there before.
• Replacement tips: support the exhaust with a jack stand, give the old rubbers a spritz of silicone spray, and remove them without levering against thin brackets. Fit quality rubber or reputable polyurethane hangers if you want a firmer hold, but avoid solid mounts—they’ll transmit too much vibration.
• While you’re there: check bracket welds, clamp condition, heat shields, and clearances around the rear axle and springs. Refit with fresh hardware if it’s rusty, and confirm there’s no binding through full suspension travel.

Given how many Jimnys spend time off the bitumen, replacing mounts in pairs is a good call if one has failed. The job is straightforward, tools are basic, and the payoff is a quiet, rattle-free exhaust and less stress on gaskets and flanges. For bolt torques and exact mount locations (mid-pipe and rear muffler vary by market/spec), refer to the Suzuki SJ410/SJ413 factory manual or an equivalent workshop guide.

FAQs

How do you know the exhaust mounts on a 1987 Jimny need replacing?
Tell-tales include a tailpipe sitting lower than usual, a knock over bumps, rattles at idle, or visible cracks and stretched holes in the rubber. If the exhaust touches the chassis or axle, the mounts are likely done.

Can polyurethane exhaust hangers be used on a 1987 Jimny?
Yes, quality polyurethane hangers can work well and resist heat and oil better than some rubber types. They’re firmer, which can reduce movement off-road, but may pass a touch more vibration. Avoid fully rigid mounts.

How many exhaust mounts does a 1987 Jimny have and where are they?
Typically you’ll find multiple mounts supporting the system—commonly near the centre section and at the rear muffler. Exact count and bracket style can vary between SJ410 and SJ413 and by market, so a quick visual check under the vehicle is best.
