- 2008 Mountaineer V6, 4.0L
So last weekend, we took an hour and a half drive and when we arrived at our destination, I noticed the Mountaineer would would make a "clunking" sound when I'd take my foot off the accelerator. This was at low speed probably less than 25 mph. It also seems to do it when shifting from 1st to 2nd gear. To me, it feels like universal joints. I took it to my mechanic yesterday, who said no issues with the u-joints. I thought it was a transmission issue since it felt like the clunk happened when it was shifting from 1st to 2nd gear on one occasion, but transmission was serviced last year and I don't experience any shifting issues. The clunking seems to occur more often if I slow down at a quicker pace versus gradually. Could engine/transmission mounts also cause something like this if not the driveline?
I had also taken it up to the mechanic since i noticed an all over vehicle vibration when we had the mountaineer up to around 65-75 mph on the interstate. The tires are new, but the tread is a bit more aggressive than what was on there, so mechanic thinks the vibration was due to tires. This same mechanic installed the tires, balanced them and did a 4-wheel alignment a few weeks ago. He is going to rebalance again.
Unrelated (I think), they noticed the right front cv boot was damp, but not dripping. It's probably a seal. They didn't think it needed to be addressed right now. I had the front and rear differentials, as well as transfer case fluids changed last year.
Any thoughts on the clunking symptoms and vibration?
