I replaced front sway bar bushings myself with Pathfinder parts. Still the same vibration, no difference before and after. Will replace other parts later.

Rear bushings need to be replaced. Got it fixed 2 weeks ago and no problems since.

Thanks for the good advice. I only replaced the front bushings just to isolate one by one. Is the rear more difficult than the front? I asked one mechanic for the front bushing replacement and his labor cost is $45. I like to do it myself if it is easy and safe.
My vibration is only felt on the steering wheel, not a entire car, and it's only a little. Will bad rear bushing affect the steering wheel only?

I replaced the rear sway bar bushings. Same vibration. My front two tires are approaching their end of life so I replaced all four tires with Michelin Latitude Tour at Costco. Vibration is all gone.
By the way, Michelin Latitude Tour is so quiet just as Tirerack and Michelin websites states.
#16 of 21 QX4 shakes very badly
Jun 12, 2010 (2:43 pm)
Hi guys, I have a 2001 QX4 and regardless of the speed it's shaking and rocking side to side. We changed the shocks, tires and it is still doing it. Today we changed the sway bar bushings and no result. What else it can be? Please help, because I am going crazy Is it possible I have to change the control arms? or someone has any other idea? Thanks

Sep 16, 2010 (2:55 pm)
my 99 started shaking and it was my brakes/rotors they werent releasing my father in law fixed it and its been 6 months or more and its starting to shake again. Took it to the shop bc it needed a tune up bad. the mechanic looked at the tire and drove it but nothing. i go pick it up and it shakes but on if your going around a curve at or above 60 mph. it doesnt shake ALL the time. any ideas?
#18 of 21 My Rocking back and forth
Jan 13, 2011 (9:43 am)
I know i need new shocks and struts but dont have the money to replace them. a lot of you have posted how this doesnt fix the problem anyways. My issue is the same, rocking back and forth... I have a 1999 QX4. I have found that the only time mine rocks is when the rpm's start to decrease (Somewhere between 2000 and 3000 rpm's, depending on my speed). its when im trying to slow down without taking my foot completely off the gas. I have had my transmission replaced from a pathfinder in a junk yard. Could this have something to do with it? I want to stress that it only happens at a certain point of the gas pedal or rpm's. Any help would be greatly appreciated.

Wow seems very similar to a problem that started with my 1997 QX4, with only 115,000 miles on it. It starts to shake really bad on turns, specifically turning to the left at speeds above 50. Sometimes on the freeway like the 405 at slight turns at 70-75 it shakes so usually it stops if i reduce speeds a mere 5-10 miles an hour. But recently at 120,000 miles its getting a lot worst.
Any ideas friends? I really apprecaite you guys and this forum. Could it be a balance, shocks, or front bushings (is there such a part or just rear bushings)?
#20 of 21 SWAYING/ROCKING '01 QX4
Jul 25, 2011 (11:56 am)
I came to this post for the same reason guys back in March 2011. I read that the problem could be bad bushings in the rear. I spoke with several different shops that suggested I should check my shocks. Before I had any work done, I took it to the Infinity dealer for a recall inspection I found out about pertaining to rust in the front strut area. (Thats a FREE inspection for you 99-02 QX4 owners) While there, I persuaded the service manager to check for anything else that could be causing the swaying. In the report/quote, there was a suggestion that the bushings in the upper and lower control arms were worn. Just to be certain, I took it to NTB to have the rear suspension rechecked (THIS IS FREE ALSO). The mechanic there was a cool guy, so he showed me exactly what the problem was. He was able to twist the lower control arm back and forth with his hand, telling me it should not be that loose. He stated that it was a special order because they could not replace just the bushings because of the task difficulty. I would have to order all four control arms. Dealer $850 parts only; Online- upper 2$175/ lower 2$125 At that time, I found someone to do the work of replacing all four of the bushings. I bought the bushings at NAPA auto parts(only local store that carried them) about $15 each. Spent $125 for labor and also had him to replace the shocks for KYB's just for extra ride comfort. QX4 rides so much better now. Problem fixed. 194,000 miles and counting; runs perfect-still looks great; still get compliments on how nice it is. This is only the second major maintenance since purchasing at 78,000miles. The first was a leak in the radiator which I replace myself.
