Rear upper & lower control arm bushings need to be replaced.
This is a well-known problem with this generation Pathfinders... the rear upper and lower control arm bushings are worn. Have them replaced and the sway should disappear.
I had a 1990 nissan maxima that use to do that and the problem was my rack and pinion bushings were bad
Broken sway bar or sway bar links.
I had sway bar links replaced on my 2003 Ford Escape. Cost- $220 w/ labor. The parts are pretty cheap of course and easy to install; it's the "book" labor that jacks up the price.
To change the sway bar bushings on a Nissan Murano, start by safely lifting the vehicle and securing it on jack stands. Remove the sway bar links if necessary, then unbolt the old bushings from the sway bar. Replace them with new bushings, ensuring they are properly seated, and reattach the sway bar links. Finally, lower the vehicle and test for any unusual noise or handling issues.
I have a 98 infinite qx4 (from what I was told its just like a pathfinder) that was swaying/rocking. I changed the whole front end and some of the back. I even got different tires, but the whole time it was the bushings. If you're able to move the Controll arms side to side that's a bad sign. The arms should be firm.
To install a sway bar on a 1995 Nissan Quest, first, raise the vehicle and securely support it with jack stands. Remove the wheel to access the sway bar's mounting points. Unbolt the old sway bar if replacing, then position the new sway bar in place and secure it using the provided bushings and hardware. Finally, reattach the wheel, lower the vehicle, and ensure everything is tightened to manufacturer specifications.
Common problem with these 2000-04 fords, there is a sway bar link (approximately 12" long) which attaches the front strut to the sway bar mounted on the cars underside. The link ends wear and cause a "sloppy" connection between the two points. This is then herd while driving and hitting potholes as a "clunk". Just replace the sway bar link and everything will be fine!
Check the front sway bar and sway bar end links. I suspect one of the sway bar end links is broken. Auto parts stores carry the replacement link kits and are easy to replace.
a clunk noise over bumps
The defective sway bar link can cause the clunking or the rattling of the noise from the front suspension during the low speed driving.
If it's at high speed it could be alignment, loose steering components, bad tires, bad rear sway bar or overloaded in the rear of the truck bed. If it's at low speed it could be a bent wheel or slipped belt on one of the tires.
