Loud bang from rear when turning

Recommended Posts

Sometimes its a very loud bang and like someone just rammed in the back of the Journey but without the actual inertia of being pushed forward.  If I slowly roll through the turn I can reduce or avoid the bang altogether.

I have had my mechanic comb through the rear end, change differential oil and inspect everything he can see and he was unable to find anything wrong that would cause this.
Also, it just so happened that I left my car at his shop a while before he checked it and he was unable to reproduce the issue, and sure enough it went days without the issue happening and I though the new oil fixed it.  It didn't.

 

I recently had my transmission flushed from the dealer and now have new fluid and filter and its still causing the problem.  I don't want to play dealer prices to have this diagnosed but I'm at a lose at this point.

My mechanic did say if I can reproduce it he would take a ride with me to understand what is happening.  I really should find time to go see him again.

with the flush DID you have them replace the filter with an OEM one or after market filter?

i am no mech but it sounds like what ever controls the  fluid pressure be the torque converter or whatever. good luck and report back on what you find when you get it fixed

I would have the rear suspension and subframe bushes checked out for play. Also if 4x4/rwd check the rear diff mount bushes. Is the exhaust maybe hitting the chassis or something?

It is AWD and the rear diff was thoroughly checked.  The dual exhaust seems solid and not doing any excessive movement.

I was thinking about my tires though.  They are pretty bald right now and I'm waiting to get new winters.  Would oddly worn/bald tires affect these AWD systems enough to cause this weird behavior?

Hi! I’m having the same problem with the bang as you described, and this is the only info online I have been able to find, even been to 2 shops and nobody sees anything wrong. I also have a 2014 Journey. My tires are all worn different too, Did you replace the tires? Was that what was causing it? If not, did you find out what was? 

 

Any info you can share would be appreciated, I don’t know where what to do or where to go. 

 

Thanks :)

Could be this Owlgirl:

 

Possibly the Viscous unit needs replacement if it is an AWD.

 

Good luck with it.  You can get it done cheaper by a mechanic, but I would buy the part at the dealer if I were you.  You could get a used one at a salvage yard.

 

I would't buy one on ebay.

 

Please get back to us to let us know if this reslvled your issue.

Take the info from the clunk topic to your mechanic.  Preferably a Transmission drive train mechanic at a Dodge Dealership to diagnose it.  Then you can get it done anywhere.  It would be nice to have it diagnosed by Dodge first.

 

Just a suggestion.

I would also suggest that you purchase the seals and fluid at the dealership.  Don't buy that junk replacement stuff on ebay etc.  You will be replacing them in a few weeks again if you do.
