chief916 Posted May 14, 2019 Report Share Posted May 14, 2019 I have a 3 axle toy hauler and the question I have is...is there a easier way to grease the under carriege. I have a zerk fitting on each side ....that's one on each side and I can't get my grease nozzle in between all the hardware to grease the zerk. Do they make extensions for grease fittings and where can I get them? Quote Link to comment Share on other sites More sharing options...
NDBirdman Posted May 14, 2019 Report Share Posted May 14, 2019 (edited) I use a flexible line on my grease guns, removed the hard line that comes on grease guns. If you can get to the zerk, you can replace it with a 45 or 90 degree zerk to hit it from a different angle. About all hardware/auto parts stores carry them. I have seen extended zerks like you are thinking but I don't recommend them, being under the RV it might be easy to bounce a rock or wood into it bending/breaking it making it a bigger pain to repair/grease.

bobsallyh Posted May 14, 2019 Report Share Posted May 14, 2019 I did the same thing that NDBirdman did. But I usually have to take the weight off some fittings to get them to take grease. Quote Link to comment Share on other sites More sharing options...
chief916 Posted May 17, 2019 Author Report Share Posted May 17, 2019 Well still no luck on getting to the zerks. I'm thinking that if I jack the frame it will take the pressure off the springs and possibly rotate the cams to maybe change the angle to get into the zerks.

I know this might not work for your inmmediate need, but when I worked in industry, we often would run grease lines to a bank of zerks, using 1/4" poly flow lines. A common bank could serve many bearings. Perhaps this could help you in the future. Another option could be to use some 1/8" pipe nipples to extend the location of the zerk to a more accessible spot.

Lance A Lott Posted May 17, 2019 Report Share Posted May 17, 2019 There is a right angle gun tip that slides on from the side. They only need about 3/8 of an inch of clearance. Also if you jack up one axle the shackles for the one will come down. Quote Link to comment Share on other sites More sharing options...

Thank you. I didn't know about this. Quote Link to comment Share on other sites More sharing options...

Sehc Posted May 18, 2019 Report Share Posted May 18, 2019 LockNLube has many products that will solve the problem. https://locknlube.com/collections/greasing-accessories/products/push-on-90-grease-coupler Quote Link to comment Share on other sites More sharing options...
packnrat Posted July 25, 2019 Report Share Posted July 25, 2019 (edited) pending your set up. a rt angle zerk fitting, (45, and 90 degree out there) longer zerk, cobble up a pipe to move the zerk to a better place, flexible hose for the grease gun, there are "other" hose connections . one looks more like a ink pin, -push up to the little check ball and pump grease in-. one looks like a super huge hypo needle, for those non greaseble tie rods. one looks just like the standard fitting, but is smaller in dia.
