So I have this 98 maxima in great condition motor and transmission wise. I had rack and pinion and axles put in brand new a few months ago. I need springs and struts so I said I might as well customize it with lowering springs since I have to swap all out. After putting lowering springs (2.25 drop front and 2.0 drop back) it makes a knocking noise when turning left at a turn light and only of pushing the gas pedal. I took of to aamco and they said lower control arms need to be replaced and transmission mount. I thought they were axles. Also after right turns going straight in second gear you'll here the noise a little bit only if I push gas pedal a little hard. This problem happen immediately after lowering car. With my stock springs it never did a knocking sound. What could of be?? Need another opinion here. Also the more weight the car has the more I would hear that sound, so I can't put anyone to drive with me

 

How about going to a Nissan car forum?
