@Mega I've had my 2017 320 a little over two years and I haven't added grease or had the bearings and brakes checked. I'm taking it in next week to a local rv dealer to have everything to have all of that checked. After reading some postings about bearing and wheel issues, I've decided I don't want to take any chances. I…
@ScottG, you make good point (especially about the belly buttons.) I've worked with a fair list of farm machinery and vehicles over the years, and barring bearingless pulleys and axels, the intent was "one or two good pumps" of grease, moving the item if possible. It was the bearing less ones (oil-lite, or steel on steel)…
After the brake mess, I went through every system. Made many repairs. Now, I have a functional 320. I like it a lot. Even the light grease used in these hubs will work for thousands of miles as long as you don't heat up the hubs. The brakes generate both heat and dust. The solenoid slides right next to the hub bearings and…
I just did a quick check in the 2017 Tab Manual page 49 that lists wheel bearings “inspect and add grease as required”. Not helpful! Then I found an old post from Mike in 2014 in reference to axle and bearings. He reported that in early 2013, the factory changed from Al-Ko to Dexter axles (and as an aside, more recently,…
In the 60's and 70's, repacking wheel bearings was not that hard. It was time consuming to clean out all the old grease. It took technique and patience to fully pack the bearing. But this was a once every 40.000 miles or so task. Sometimes people forgot, or tried to get just a few more miles before the maintenance. That…
Be careful with just adding grease. You can put in too much and damage the seals. If you have the Dexter E Z Lube type you change out the grease by spinning the wheel as you put in the new grease. The wheel turning forces out the old grease and the new grease is moved in to replace it. It is very easy to do this. Just…
@MuttonChops Thank you for the graphics and excellent explanation. I was trying to say the same thing earlier, but not near as well as you put it. The graphics helps a lot also. In regards to blowing out the inner seal, I guess the question comes down to the path of least resistance. If the old grease had become hard and…
You are welcome. :) No idea if anything could be seen with a mirror. I've had EZ-Lube Hubs on two boat trailers in the past and never had issues or even spoke to anyone having issues with the inner seal failing. Would think keeping to the suggested maintenance schedule is important, so the old grease does not start to…
@DougWW, I believe there are at least a couple other threads on this topic. You might want to search around, but remember that opinions are like, um, belly buttons--everybody's got one. ;-)It seems to me that using the EZ Lube zerk--and actually pushing all of the old grease out--would be pretty close to a manual repack.…
If I bought a used unit, I would want to disassemble the hubs, re-pack the bearings and check/adjust/repair the brakes. There are several reasons for this. One, as you have experienced, problems might exist. Two, without a maintenance history, I would not trust anything other than a complete service to insure that…
