Loud clunk in reverse on Inclines

Every time im parked on a incline and go to put my jeep in reverse, I hear a loud clunk and can feel it in brake pedal. Not sure if thats normal or not. Obviously putting it into gear on an incline would put some strain on the tranny. Jeep is a 14 v6 laredo.

Random unrelated question, when I close the liftgate it sounds like there is a loose bolt insade that makes a rattling noise. Just mention that at next service im guessing.

When parking on an incline it's best to use the parking brake. These are heavy vehicle that are resting on the Park prong. When I park I always come to a stop, put it in neutral, set the parking brake and let out the normal brake so the weight is on the parking brake. Then just shift to Park and now you won't have a clunk when shifting out of P on an incline.

Don't forget to reverse the process, leave the parking brake on, shift out of P then take the parking brake off.

This process has become second nature to me because I used to drive a standard so setting the parking brake when I parked was the norm. If you were to check in the manual most manufactures, your Jeep included, will state the use of the parking brake is recommended when parking...go figure.

Re: Loud clunk in reverse on Inclines

I've been having similar sounds and feeling in the brake when I shift into gear from reverse on even the slightest incline, sometimes.

Took it in to the dealer and they said there were no problems they could find, so who knows what it really is.

If it does it all the time you may have a problem with some bushings. If it only does it on an incline, when the vehicles weight is on the transmission, then I wouldn't worry about it.

It doesn't happen all the time, just on occasion and it's usually at an incline, but only a slight one. Nothing like a steep hill...only shallow driveways and such so far that I've noticed.

Would it be something that I hear/feel when backing up too if it was the bushings? Sometimes I feel some quick pulses in the brakes and a scraping noise when I'm in reverse and have my foot on the brake, usually when I've heard that noise changing gears and on a slight incline. This was also brought up to the dealer, but they couldn't find any problems or had heard of what I was experiencing.

Doesn't really sound like anything to out of the ordinary. Even on slight inclines you still have a heavy vehicle resting on the park prong.

I wouldn't bother with a dealer unless it's easily repeatable. YMMV

Re: Loud clunk in reverse on Inclines

Revisited this lovely noise today, while shifting into reverse, at a stop on a pretty steep incline in a parking garage.

It sounded like a gunshot and the people near my Jeep looked like they were thinking the same thing.

Do not like.

Re: Loud clunk in reverse on Inclines

Glad I came across this thread. Noticed the same thing when getting out of my driveway which is slightly sloped. It's a pretty uncomfortable thump sound. I will try to remember to use the parking brake until it becomes a routine.. It totally makes sense from the mechanical standpoint - a VERY heavy vehicle resting on the parking prong isn't the best thing.. I was wondering why cars still have that parking brake thingie that nobody uses since you can just put it in the "P" position

I also wonder if you can damage your transmission if you never use parking brake on an incline.

Now a whole other thing is to explain this to my wife and actually make her remember it...
