I think there was a C clip that you are probably missing.
I've had the leveling kit for just over three years. Last year the front right axle started to leak. I took it in(with the leveling kit installed) and they found that the clip had most likely failed. The entire front end was replaced under the powertrain warranty.slice07 said:hey everyone...... well heres the deal. i pu ta level kit on my 07 titan. and i'm not sure if i did it then or what. put i noticed some oil dripping down. well i got up under my truck and noticed on my passenger side the axle is pulled out about an inch. i remember it saying not to pull to ohard or the axle might come out when i was putin my level kit on. i was thinking that there was just a like retaining clip and it wld just push back in. does anyone know? i'm trying hard not to have to take my spacers off just to take it the dealership. anyone have any suggestions?
