The chain on the FJ was making "klonky" sounds so I decided to change it. My records show that its done 34,000 miles. The FJ is generally not used in bad weather so that had meant the chain has lasted. The chain came with both spring clip and rivet links. I always use the rivet link so that there's no way it can come loose. I make the chain endless then fit it. This means that I have to remove the swing arm. This isn't a big job and it allows me to lubricate the suspension linkages and touch up the paintwork on the arm.
