Low speed intermittent noise November 09, 2021, 03:41:03 pm My 95 LD on a chevy chassis has a groaning noise that is intermittent at low speeds in the rear end but hear nothing over 35MPH, I'm about 300 miles from home any ideas?
Re: Low speed intermittent noise Reply #1 – November 09, 2021, 07:18:44 pm Is the rear axle full of clean fluid?Have you checked the driveshaft's u-joints and carrier bearing lately?A sticky rear brake or brake cylinder is a possibility.Rusty rear leaf springs.Without hearing it and knowing more, that's the best I can come up with offhand.Larry

Re: Low speed intermittent noise Reply #3 – November 10, 2021, 12:05:43 am Maybe pin it down more: does it make the noise accelerating, or when you let off the gas? My guess is a u-joint. They can be checked more easily without tearing anything apart. Just crawl under with a good flashlight and wiggle the drive line. How many miles do you have on the drivetrain? RonB

RonBYou need to have the wheels chalked and the transmission in neutral, freeing the driveshaft of preload, before checking for loose u-joints.A better description of the noise would be helpful.
