Re: Howling while accelerating

The cost for a new diff is probably a lot more, plus the labor charge to swap it. I used OEM Timken bearings with the first rebuild, and they only lasted 50k before one went bad. The second time I used SKF's (Sweden made) I also replaced all 4 hubs/wheel bearings with SKF's, which are better than OEM Timkens.

Re: Howling while accelerating

Make sure to replace both of the side carrier bearings and the pinion bearing, and not just the one bad one. Metal particulates from the bad bearing will cause the other bearings to wear too.

I order this differential carrier in case that the damage is greater. Or it can be only bearing and costs less. But this week I take the mechanic to open the differential and look inside. So let's see. Thank You.

Re: Howling while accelerating

The picture shows the right-hand side spline axle shaft touching the differential cross-shaft (pin). This is not normal! Any Thought??? Has anyone ever had this before? Thank You

Having the end of the axle right up against the center pin is a wear issue. Unless you put a feeler gauge between the two to check the clearance, it may not be right up against it. This not the source of the serious noise from your assembly. I also have a 4.7 05 and the service recommendation for the axle fluids is a ridiculous 12k miles. I try to do mine every 25k to 30k or so.
With the limited slip rear, an additive along with the fluid is required. Without the additive, the rear will have issues.
But, having had a 2000 Grand Cherokee with a rear that sounded like a jet plane was following me, I know your noise sounds like a side carrier bearing. The 2000 had to have the bearings replaced three times before I traded it in when the extended warranty was up. Each time it was dealer repaired.

Re: Howling while accelerating

This is a wear issue. Place a feeler gauge between the two to see if it's totally up against the pin.

Actually, My mechanic thinks that the right-hand side spline axle shaft is touching the differential cross-shaft (pin). But in reality if someone knows and has looked inside the diff maybe can tell me if this axle shaft at the right goes closer than the one on the left. Closer but not touch I guess. We aren't sure yet.

I found this video on you tube that show the rear Diff and the right side spline axle shaft looks closer like mine. Here the video :

Thanks Guys.

Re: Howling while accelerating

It was the pinion who had lost the nut that adjust the torque creating damage on the bearing. I bought the Yukon Gear & Axle Differential Rebuild Kit on my local AutoZone for $207.75 with taxes. My Mechanic also said my rear left axle seal was leaking so he installed all Seal and Axle Bearing for $350.74 Labor. Total of $558.50. Here the Kit set Screenshot by Lightshot

Thanks for your comments.
