Loud Grinding During Acceleration

Hi Everyone,


I have an 2002 4X 6 cyl Escape with 112,000 miles. I have had no major problems with the exception of new front bearings being replaced 6 month ago. A couple of days ago I experienced something that has me baffled. During acceleration I get a low rumbling sound from the driver side front engine compartment. It does not happen in reverse only in drive. The sound goes away once the car gets to 25 MPH. I checked the CVC axles and the boots are fine no clicking of the CVC's.. I am just hoping it's not the transmission. Has anyone experienced this and what was the fix?

Hum

Would the inner CVC joint make the same clicking sound as the outer CVC does when it is going bad? I just hope it's not my 1st and 2nd gears going bad...

I think I found the issue. A friend mechanic took a test drive in the car and not 2 minutes into the drive he said motor mounts...Has anyone ever replace them? It doesn't look like too hard to do. I found 3 mounts. Is there 4 mounts the book doesn't say specifically how many? I am thinking two tranny mounts and 2 engine mounts.

It would look like you are having a conversation by yourself. I hope that your solution works for you. I have not replaced mounts on these vehicles, but when I read your first discription of noise in forward nothing in reverse, I was thinking motor mounts. Three or four mounts sound about right. Although mounts usually are described as a thumping type sound, a rumbling sound would lead me to check for an exhaust leak at the manifold.

Loud Grinding During Acceleration

Thanks for the reply...It's a habit of mine talking to myself. Kind of makes me think things through. My friend said that not all the mounts would be bad. That only the one that stabilizes the engine during forward acceleration may be bad. Which makes since because once my speed gets to 30 or so it smoothes out? I am thinking less engine movement. The front mount is $80.00 and the rear $164.00. There is also right and left mounts which I have not priced out. My friend also said that if I don't replace them soon it would possibly damage the driveshaft. I have it parked now and will replace the mounts this weekend and let everyone know the outcome.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

The problem being back lower motor mount. Since the original poster didn't follow up, I am responding with the cause & solution. On my 2001 escape v6 it had a broken bolt on the motor mount from when I had my tranny/torque converter take a ****. The mechanic put back the bolt on angled. So in due time I HIT a dip & I knew I heard something bust but didin't know exactly what it was. Week later step on gas, grinding sound coming from motor/torque converter, I do mean grinding. Long story short check motor mounts!
