Let me first say thanks helping me out.
To start.... I have a 99 xj that has 76k miles on it. It came stock with Dana 30HP in front and a 35 in back with a np 242 and an aw4. The gears are 3.55
I saved my pennies for some time to build a solid adventure rig to get away when I can.
I found a Dana 44 for the rear from an 87 xj.
Since I have no shop and my skills are fair, yet not expert I chose to have a 4x4 shop I felt was reputable to do the work so I can be sure it’s right.
It was suggested, and I accepted, new nitro 4.11 ring and pinion front and rear. I also got new nitro rear axles. And Tera flex disc brakes.
No I’m not made of money... I just wanted a clean new build to start from.
The rig was lifted with rubicon express 3.5 super flex and an advance adapters SYE.
New front ball joints, and any other suspension/steering parts that it needed.
Now here is the rub.... they had the rig for 2 weeks (14 solid days) and I couldn’t afford the rental car anymore. They said it was safe to drive yet needed some adjustments.
Got going down the road about 10 miles and as I slowed to a stop I have a whirring noise on deceleration. I called them and was told it might need the 4 degree axle shims changed to 6 degree shim. Also the new disc brakes are setting in. As the truck got warmer the noise got louder on deceleration. I took it back and they added new longer leaf pins and 6 degree shims.
I head out again and now it sounds and feels like I’m driving on super swampers on acceleration and cruising and the whirring is even louder on deceleration to a stop.
As I drove it that day the whirring is all the time now. Acceleration and deceleration.
Cold or warm.
I called them and was told that there might be something wrong in my transfer case...yet there was nothing wrong before I handed it off to them.
Also told the shims are at their max and the next step is to re weld the spring pirches to get better angle.
I’m at a loss. Is it SYE, transfer case, spring shims & pirches, or did the ring and pinion get set up wrong. Still can’t get an answer from them.
I Need to take it back to get sorted out or it’s all a waste.
I’d like to get some feedback from everyone on possibly what the problem is.
I’d like to trust this shop to do right.... and I’d like to learn more
Any help would be appreciated.
