Something is popping

[jeepguy_902003]

When I'm driving it pops kind of like a thunk in the front just every once in a while nothing steady. Sometimes when I come to a stop and sometimes when I'm just driving straight no load on her. It doesn't do it when I mash the throttle or when I let off of it. I just got back from base. It's 12 miles to base drove around base and through about 2' of snow for about 1 mile. 12 miles back and it popped about 6 times. Only once that i felt a good vibration in my right foot. In 2WD nothing happens and in 4 LO nothing happens. At least there's no popping. It never happened once while I was driving to base or back. Seems to do it more when the transmission is cold. I don't know what to think.

jeepguy_902003,

what type of jeep tp you have?

 

[jeepguy_902003]

1990 Wrangler YJ with a 258 power plant with a Chrysler 999 auto. Not happy about the transmission but I just got the Jeep a couple months ago. It has a NV231J t-case, Dana 30 in front and a 35 in back.

hi everyone, its been a while

I might be grasping at straws here, but I had a dull pop that would only pop occasionally. I searched for weeks, but I finally discovered I had a broken motor mount.

This was in an older CJ5 with a V8, so I don't how it will apply to yours.

This is off topic but eagle river is a fine town, I have some family that lives in wasila, and I love it when I get the chance to go up there it's great.

Sounds like a stretched transfer case chain or a broken transfer case housing, allowing the chain to slip. I think the loud pop is the chain slipping. I hope I'm wrong.

I Finally got my Waggie

I hope you are too Bounty, but you would think it would do it with a load. I get no pops going up hills or just stomping on the gas when 2' of heavy snow.
