I have noticed a TSHH TSHH TSHH sound coming from the rear of the car. Took it to a mechanic who told me he thought it was the diff ($$). Another said it was the brakes. I jacked the back up and took the brake hardware off and re-installed the wheels and ran it up on jackstands. The noise was still on the outside but no brakes to cause a rubbing sound so I figured the noise was a bearing issue. I used a stethoscope and could hear the noise more prominently from the edge of the axle rather than closer to the diff and it was pretty obvious where the noise was coming from.
I went shopping on Rockauto and saw separate bearing and seal - like installed on the car, as well as a combo of a bearing and seal in 1 assembly. I liked the combo setup so ordered that and got a bearing puller and slide hammer to remove the old parts. Got 3L of Amsoil 75W140 oil and the additive and watched a few Youtube video's of axle removal and away I went. Got the old bearing and seal out and installed the new combo assembly. As per the installation instructions, I inserted it until it bottomed out (different noise when tapping on it) and it stuck out a little less than the 1/4" as specified on the instructions. Great! Re-inserted the axle but couldn't get the C clip back on (inside the diff). The axle wouldn't go in far enough. F'ed around a bit and tried to knock the combo in further but it was in all the way so then decided to remove the new combo bearing and seal and re-install the old bearing and seal (fortunately the seal came out without damage when I pulled the bearing out). Added some synthetic grease to the bearing, refilled the diff and installed the rest of the parts. Much less noise now so fortunately bearings were the issue and not the diff and the grease will probably keep them quite for a while until the diff oil washes it out - but I still want to install new bearings but that of course means another 2.5L of $$ oil in the diff so I'll wait a bit. Has anyone else tried to use the combo bearing and seal? The parts were Timken 'made in the USA" so I trusted that it would fit. Will try a return to RA. Any advice or comments appreciated.
