ULB --

I did take it to the dealer quite a while back, but according to them
it's another one of those "normal" things that a jeep does. They took
a ride out in it with me, and did hear the noise I was referring to.
It very well could be normal since I have heard it since I bought it
new. They told me not to worry that it was completely normal.

Also, I noticed that today after my gas tank got to the 3/4 tank full
mark, the noise I was describing in a previous post that I thought was
pinging completely went away again. Seems to only do it until the
first 1/4 tank of gas is used up. This is the second tank in a row
that it has done this then quit like that. Then it quits. I also
discovered that the 'pinging/tapping' noise I was hearing that sounded
like my side windows flapping on the metal support bow was indeed just
that. The wind was a bit stronger today than it has been the last
couple of days, and it was flapping faintly and heavily -- each time
when the wind was blowing. One down, a couple more to go. : D

ULB --

I did take it to the dealer quite a while back, but according to them
it's another one of those "normal" things that a jeep does. They took
a ride out in it with me, and did hear the noise I was referring to.
It very well could be normal since I have heard it since I bought it
new. They told me not to worry that it was completely normal.

Also, I noticed that today after my gas tank got to the 3/4 tank full
mark, the noise I was describing in a previous post that I thought was
pinging completely went away again. Seems to only do it until the
first 1/4 tank of gas is used up. This is the second tank in a row
that it has done this then quit like that. Then it quits. I also
discovered that the 'pinging/tapping' noise I was hearing that sounded
like my side windows flapping on the metal support bow was indeed just
that. The wind was a bit stronger today than it has been the last
couple of days, and it was flapping faintly and heavily -- each time
when the wind was blowing. One down, a couple more to go. : D
