I used a small round file to create a chamfer or groove at the hole.
No trouble initially and I shall see in the Spring if all is good.

Sounds good.....I was thinking of using a small diegrinder wheel or ball and just do some minor relieving. I wouldn't want to take too much off in fear of weakening the bolt shaft. rockin'

I am of the opinion that grease is way cheaper than parts, so I grease 1 a week when I am on the road. That said I have replaced the bronze bushings 3 times now they only last about 20,000 to 25,000 miles I have heard that the never fail bushings are better but I have reservations because nothing lasts forever.

Good tip... Had a similar issue this year on two zerks. I replaced the zerks thinking they were rusted up bit didn't fix the problem. Based on a tip I got here earlier this year taking weight off the suspension allowed me to pump grease in.

This is what is on our alpenlite. I had the older ones replaced when the new springs were installed this summer. The older bolts were the greaseable also.

Gib3633 sorry about your troubles, but I still don't understand what you mean when saying the bushings was stressed after 70 miles and why you would try to regrease after only 70 miles. I fully agre a heavy wehicle neds to have heavy duty suspension, I have read that someone drilled the hole wher grease enter bushing larger to make it flowe easier. I hope you are getting you proplems sorted out

Slowmsy; You didn't read correctly. I said I greased them before putting any weight and they took it well. I drove 70 miles and had a struggle. This 15000 lb. unit came with wet bolts and wouldn't accept grease then either. As I said and still say those bushings are not heavy enough for a 15000 lb. trailer. The bolts and shackles are fine it's the bushings that can't cut it. PS it's only cold in the winter in Ontario. It was 70 degrees farenheit in september. Before changing them I jacked up took weight off pryed back and forth and couldn't get to accept grease. When I change the bushings the were so thin I couldn't remove using bushing driver . I had to peel them out. The new ones were installed using a bushing driver and a press. I don't know of any better process than that.
Gary Wheeler from Mor/yde sure knew what I was talking about and offered me the solution. That was IS suspension and Disc Brakes. Incidentally these were the most straight up honest people I have delt with since got into RV ing I haven't had any use since I came home in April due to a Triple Heart Bypass surgery. I put a second AC unit on today and I think I should be in for an enjoyable winter

I had one fitting that wouldn't take grease. Had to jack the wheel up a little to remove the load.

IMO the amount is not the issue, the frequency is more important.
