Hi,
I am trying to diagnosis a vibration. The vibration is only apparent when coming to a stop. With or without the clutch in. Even when costing in neutral. It starts to occur at about 20mph. Continues till the truck is stopped. It's hard to describe but it feels like the abs is trying to kick in. I am coming to a slow stop, no possibility of impending brake lock up.
It's intermittent, started a few days ago.
Until this time the truck was perfect. It's a 2004. 5 600 with 3:73's and a 6 spd. Just turned 40,000 miles. Driveline is totally stock. Tires are BFG's. No recent work done to the truck. No hard tows. Towed about 2500#'s to 2 bike rallies recently. I am the only driver. No burnouts, no banging gears ect. The truck leads a charmed life.
Any ideas appreciated.
So Far:
I pulled all the wheels and checked all the brakes and calipers. Brakes are like brand new. No seized pistons in calipers.
Checked all fluids. Rear dif, Front dif, nv5600, and X-case. All fluids appear to be in good shape visually. Color normal and after pulling a sample no evidence of metal shavings. Fluids in difs were changed at 15K. nv5600 & x-case fluid is original fill. I actually was going to be changing fluids on Saturday, the vibe started Friday after work pulling into the driveway. The wife was in the truck and she yelled, push the clutch in. That's what the vibe felt like. The first time was the worst.
I haven't pulled the driveshafts but there is no apparent play in any of the u-joints.
Can I run without a front driveshaft for troubleshooting purposes?
The steering gear feels tight. Knuckles, the u-joints, on the front axle also appear tight.
Like I said. The first time it happened was Friday after work pulling into the driveway. That was by far the worst. It felt like I tried to stop without pushing in the clutch. From that time on it's very slight. Almost feels like the abs is trying to kick in. But I don't feel chater in the brake pedal. Never used abs in this truck so I'm not sure how bad the chatter is in the pedal when the abs cycles. I'm going to try to hammer the brakes and engage abs when we get some rain. Starting to think I might be imaging things. Any ideas appreciated.
