Onyx610 Posted November 11, 2021 Share Posted November 11, 2021 I have always wondered what the clicking noises are when you turn the key to accessory and can’t find any info on it. Usually about 4 clicks on the RDs. Two in the front and two in the back. On the CVs it’s all at once. Sounds like a bunch of starter solenoids.

Onyx610 Posted November 11, 2021 Author Share Posted November 11, 2021 Awesome, I appreciate the info as usual! Should you also hear 6 clicks instead of 4 then if it’s a tandem axle? Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted November 11, 2021 Share Posted November 11, 2021 (edited) Most ABS is only four channel.That means on the rear there is only two sensors for the four wheels. Edited November 11, 2021 by theakerstwo 1 Quote glenn akers Link to comment Share on other sites More sharing options...
