When I decide to press out the bearing on Idler No. 1, I will post up the information on that as well. I have a sneaking suspicion that Idler No. 1 uses 2 of the bearings that Idler No. 2 uses.
Saw this canuck on youtube clean and repack sealed bearings.
The plastic seal pops right out with a razor blade and pops right back in with your thumbs. I used WD40 to clean out the bearing. There was a significant amount of dirt and rust inside, but a good WD40 bath cleaned it right out. I then packed the bearing with new Mobil 1 grease, popped the plastic seals back on, and I now have brand new bearings. There is another video I watched where a guy opened a brand new sealed bearing and found that they use white lithium grease from the factory so replacing that grease with Mobil 1 wheel bearing grease will make a huge improvement.
This is the only way I am going to handle idler pulley issues going forward in the future.
This makes me understand now why the idler pulleys dont last for shit anymore. Needless to say, I removed that gel crap and packed the bearing with Mobil 1 bearing grease and reassembled it. After this discovery, I think I will be taking all my new idler pulleys back off the vehicle, repacking them with real grease, and putting them back on the vehicle.
I would have gotten pics of this gel that was in the bearing, but my hands were covered in grease and I didnt feel like touching my phone.
In light of all this research I have done on these bearings, I now have a complete spare set of idler pulleys, all repacked with Mobil 1, as spares in the garage. I also have two brand new bearings as well so I will not be buying any idler pulleys for quite some time
My FJ December 29th 2018 Beat that California!
Found that the bearings had got muddy water in them as the grease had become a nasty brown color. I cleaned the bearings out with some carb spray, repacked with Mobil 1 grease, and re-installed. Just like new. Best part is it only cost me about 30 minutes of time and $0.
I’ve had zero issues with my bearings since the clean & mobile 1 repack done in early June 2019. Not even a small squeak exist after almost a full year of abuse through water, mud, dust, and repeat! Now that the repack has stood the test of time with my driving “style”, I doubt that I will ever waste money to buy new replacement bearings again!
