I brought my 2005 LR3 (90k miles) to an independent mechanic for replacement of both rear upper control arms (which were quite rusty). The process required some grinding and cutting, resulting in an inadvertent nick of an air line on the rear LEFT side of the truck. A repair kit was purchased and that air line was fixed. After the work was complete, the air suspension reflated at all corners except the rear RIGHT one. I had experienced no issues with suspension function before this. The mechanic is working through some troubleshooting but I was wondering if the LRForums brain trust had any relevant experience to impart. Thanks in advance for your shared wisdom.

 

Well you either have a leak OR the rear valve block was messed with and the lines hooked up wrong. Thats about it, pretty simple system.

 

You were right. He found a leak in the air line on the right side (somewhat hidden up in the body). Repair kit fixed it. Back in action. Thanks for the wisdom.

 

More wisdom - avoid that mechanic. The air lines are not in a position they can be easily damaged when doing the back end. The gavel block is close, but its very obvious it can be simply lifted up and moved with no tools.
