I had that problem with my LBZ last year....didn't have warranty but decided to get lines replaced with better fittings.
It's a bit of a drive but I had some other work done while I was there...
Where to start?
VDI
Twin Air air filter
EPI or Dalton clutch kit
heated grips
wheels
tires
bumper
Highlifter springs
1.5-2.0" lift kit
Highlifter rad and relocation kit
exhaust
rear box
tow rope
full snorkels
skid plates
another set of wheels and tires
grease zerk mod
front suspension shim mod...
If you like the Mudzillas then look at the Super Grip Mud Bitch....same tread, lighter, and harder tread compound. Rej is a local guy who is great to deal with!!
The later LLY's are pretty much the same as the LBZ. internally and programming wise. They do only have 5 speeds instead of the 6 the LBZ does.
Are you looking specifically for a crewcab? My dad has a VERY clean 04 ex. cab SB with 92xxx kms, never been modified. Spray in box liner, Truxedo...
I have an '07 KQ 700 that is modded and it has been a great quad. There are some issues but I am very happy overall and am glad I went with it instead of the Griz 700.
It's all a matter of taste...you know the Chev, Ford Dodge thing.
