I have a 2003 grand Cherokee limited. Recently my jeep has been making a low humming sound and vibration at high speeds. Its also drifts like if its got a lose or dead spot in the steering wheel at high speeds.

Asked by Armando Dec 11, 2014 at 09:42 PM about the 2003 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

I've already changed a lot of parts due to a similar problem. I changed all four tirod
ends,both front wheel beerings,the ball joints in front, the track bar,right&left CV axels,also
rebuilt the front drive line. I just got new tires and had the balancced twice. I've had the
alignment done twice as well. So as you can see I could really use some more ideas of
what it can be. I'm leaning towards a bad steering stabilizer or calipers flexing or possibly
a bad spring&strut. What do you guys think

I think you may need to check the steering gear box,or rack and pinion,which ever your model has.

The humming may be coming from the power steering pump,straning to keep fluid pressure on the gear box/rack and pinion.

The gear box could defanatly be the corporate. I'm going to look into how to check it. Thanks for the help

I have a 1995 Grand Cherokee Limited and I am randomly getting front end noise. This can be a rumble or even a howl in the driver's front wheel with vibration. This happens at random and I just never know when. Ths is a AWD NP249 TC and we have replaced both front and rear drive shafts, both cv axles on the front end.The transmission was recently rebuilt about 4 months ago too. I just have no clue what's causing this and it's hard to pinpoint when it happens randomly then after cutting car of will be ok later. I'm thinking perhaps differential but would like an expert opinion. 2 Answers
