DIY Muffler Replacement for Samurai

The Suzuki Samurai, with its 1.3-liter engine, has a muffler with an integrated front and rear exhaust pipe section. The front runs from the head pipe or exhaust manifold to the muffler body and the rear from the body to the tailpipe just above the rear axle housing. Replacing the muffler requires you to remove several bolts at the front of the system and one exhaust clamp. The job can be completed in the driveway at home in about an hour with common hand tools.

Instructions

1

Raise the front of your Suzuki off the ground with a jack and position a set of jack stands under the front axle housing to support the vehicle. Make sure the jack stands are on a flat, solid surface, then remove the jack from under the truck.

2

Locate the flange at the front of the muffler assembly from under the truck. Remove the two mounting bolts from the flange using a wrench on one side and a socket and ratchet on the other.

3

Move to the rear of the assembly and locate the connection between the tailpipe and the muffler assembly. Remove the nuts from the exhaust clamp on the pipe with a socket and ratchet. Remove the clamp from the exhaust pipe and discard it.

4

Separate the muffler assembly from the tailpipe, then remove the muffler from the rubber hangers under the truck. Lower the muffler to the ground and remove it from under the truck.

5

Raise a new muffler assembly into place and connect the two rubber hangers to the support pins on the muffler assembly. Raise the rear of the muffler assembly and slide the tailpipe and the rear connection of the muffler together. Install a new exhaust clamp on the connection and tighten the nuts with a socket and ratchet. Do not over-tighten the nuts or you will crush the pipe.

6

Position the flange at the front of the muffler assembly against the flange on the front exhaust pipe and install the two retaining bolts. Tighten the bolts with a socket and ratchet on one side and a wrench on the other.

7

Raise the front of the truck off the jack stands with a jack, remove the jack stands from under the truck, then lower it to the ground.
