I have followed everyone's advice and waited to find a good truck. It has finally paid off, found a very low mileage (<60k) southern truck that has been well maintained. The seller and I have negotiated on the price but I still needed a good inspection. We did an oil change/PPI at a local lexus dealer and it came back very clean except for having torn CV boots (due to age) and slight weeping coming from the rear AHC shocks. From searching on here I was able to tell that all I have to do is order the $45 kit for the CV's which isn't too bad since they are in good shape. I'm not sure what the AHC shocks entail, what kind of bill am I looking at? The dealer recommended to replace the shocks but I'm sure they are in good shape, maybe there is a simpler fix (similar to the CV's). I'd like to keep AHC so please don't recommend OME shocks etc. Thanks guys! Once I get some answers I'll be closing the sale today.
CV boot and AHC Shock Leak, costs?

AHC shocks rarely fail, but they do weep if the neutral pressures are too high for to long. I would bet my brother's left nut that this is the situation with the vehicle you're looking at. Ask the dealer to hook up techstream and tell you what the front and rear neutral pressures are, adjusting torsion bars to lower the front pressure is a built in feature and new rear coils with spacers to lower rear pressure will run you appr. $200 plus labour if you pay someone to do the job.

Congrats on your purchase. Did you have the dealer run your neutral pressures? If they are high for a protracted period you may get weeping at a shock or two. There are two seals within the shock that ultimately can leak and an o ring seal at the top flex to rigid fitting clamp that can leak, however shock actuator failure is rare. If your compression/rebound damping is good and you have passed the "reservoir graduation count from L to H test" then you should be fairly confident your accumulator globes are still serviceable. A little AHC fluid can go a long way, I'd recommend cleaning the weeping shock body and monitor to see if you actually have something that needs to be pursued. Often weeping AHC shock actuators self heal when neutral pressures are reduced, at least that's my experience.
