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)?

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.

I am having the same issue with my 2001 Infiniti QX4, I really don't want to buy a new vehicle or used, but it is hard to find a trustworthy mechanic locally to fix things on my vehicle. The mechanic you mentioned just replaced the bushings for you or did you also have him replace the control arms? I found Control Arm Kit - Left and Right Control Arms on carparts warehouse.com for $128.25. I could not find the uppers that you mentioned on their site. The one they show in the kit is for Front Lower Control Arm Pair - All Models. So my question is, if I buy the control arm kit I listed here, will that also include the bushings you spoke about that you bought from NAPA? Or did you only have your bushings replaced?
I also want to mention that my check engine light came on about a month ago and when it would come on, I noticed the car would idle rough, the codes mentioned spoke about a misfire in the coil and another code that mentioned there could be a slew of other stuff needed to be replaced. I am unsure what to do as the dealer said $800 bucks to replace all the ignition coils.
My mechanic also mentioned I needed to get my rack and pinion replaced. I am wondering if the rack and pinion is causing the car to rock from left to right. Either way, I have found the parts on the same website, but my problem is finding a mechanic that knows what he is doing.
Any feedback would be great.
