If the hatch is sagging you can replace the struts.Is the tailgate lift height adjustable? I spent some quality time with the owners manual but didn't find anything. I would like to not have to duck under the tailgate - I've hit my head on enough tailgates over the years.
On a separate note, it was rather amazingly difficult to find the tone controls for the stereo on the LX. WTF?
The tailgate has wire cables that set its lowered position. Some have replaced with new. Others have changed the lowered position by shortening the wire cables (handmade new ones usually)
