Our Mo now has 170k kms and for the last few months I've noticed a wobble or shake in the rear when driving on the hwy, it happens when the pavement is uneven or if I go over a bump. It's getting worse than b4. It feels like something in the rear suspension is loose or worn. I checked for any play in the tires (top-bottom and side to side) while jacked up, they are all tight with no play.
I've recently replaced the front lower controll arms and rear shocks. Maybe it's time for rear controll arms or...? Anyone notice sometiing like this?

It's not a up and down shake. It's side to side. Bad shocks make the car more bouncy. That's not the issue here. It's almost like when the rear end is sliding on ice or something..if the pavement isn't nice and smooth it really shakes things up back there. Definitely not the shocks.

I remember a long discussion about this in some other threads, but not the solution. It might help to search for related discussions.

Then check the rear alignment, especially rear toe. Be sure they check the thrust angle (the angle the rears are pointed relative to the fronts).

I was gonna suggest 4 wheel alignment as well. I remember a couple of members saying their rear feels like it's bouncing all over the place making it hard to control when hitting bumps or under hard acceleration. Do you have awd?

That could do it. When I picked up my new 2012 from the dealer and drove it home, it was bouncing all over the road. Checking the tires, I found approximately 50# of air. When I reduced the tires to 35# it smoothed right out.

Good idea to check! Tire pressures make a significant difference in handling.

That was the first thing I checked. I wish it was that simple.

It's been getting worse over time. I noticed it when I first bought the Mo but it wasn't as bad as it is now. Also it wasn't as noticeable (but still there) when I had the 18" winter tires on. Way more unstable with the stock 20s

FYI -

I have had the rear shocks and coil springs replaced.

3 different types and sizes of tires.

Different inflation pressures.

Different toe angles.

Nissan service techs have been no help either.

None of these has helped. Again, I'm sorry and I feel your pain.

Curious Jazz - does your Mo have tow package?
Thx for the links. No tow pkg.. No accidents.. No off road driving.

Just doesn't make sense for it to become worse over time. The bump steer in ur threads is something I noticed when I first bought the car and I looked past it.. Now it's hard to ignore.. Almost don't feel safe when it does it.

Nissan dealer had a look.. Said the only thing they see is that the rear shocks I just replaced are leaked out again.

There's a warranty on them... They are Monroe OESpectrum light truck. Supposed to be a good brand! Isn't ur odd that they both failed within a month or two of installation? Has this happened to anyone before?

Yes. Another member had reported multiple shock failures within a short period of time. That is why I had mentioned to check your rear shocks earlier.
