Ok, I found a guy who is selling a XT-6 that he says has some minor issues. Here is what he says is wrong:

Air suspension is going out, Seems to have a problem with fuel delivery. Runs for a while then seems to putter.

That is what he has listed as problems. It is a full time 4wd car with 131,000 miles. I need to know if there is anything else to look out for on a XT-6? I have owned 2 XT's but never a XT-6. I imagine a full suspension swap should be done. What will work for the suspension conversion? Any help would be appreciated. Thanks,

Richard

yes a suspension swap to coil overs is the best option for sanity. truthfully the air suspension rides awesome and is cheap and reliable since you can set them up to never need the struts replaced. but that's a pain to get the car that far - replacing 10-20 orings, reconditioning the struts, etc.

 

tons of conversion and XT6 specific information on subaruxt.com. there's quite a few options and different ways to do it. basically there's no "simple" solution that you can just go buy and bolt on. FWD XT6 coil overs are a direct swap but the car doesn't sit level, you can flip the rear strut mount to bring it down an inch or so but it's still a little high in the rear. car ends up sitting much lower than with air suspension as well. more options and info on subaruxt.com.

 

the stumbling could be anything - simply ignition related - plugs, wires, cap, rotor.....any number of sensors - CTS, TPS, MAF....or bad headgaskets. hard to say.

 

in addition to standard used car items to check...fluids, axle boots, check for clutch condition when you're driving. nothing like buying a used car and finding out it needs a clutch.
