The engines have a few issues. One being the valve guides loosen in the head and cause valve train/rocker issues. The other being they can sludge up if not maintained well. You can swap early used engines into early Libbys, but not late to early. The JTEC controlled engines won't interchange with NGC controlled ones. The way to distinguish is the JTEC engines have 3 PCM connectors where the NGC have 4. The reason they won't interchange is the tone wheel for the crank sensor is different between them and isn't swapable. (sp?)
The lower ball joints have a bad habit of popping loose out of the lower control arm. There was an ongoing recall on them for many model years. The window regulators are very prone to failure too.
I'd have one in a second if the price was right. They ride well and are a good size IMO. But look out for the aforementioned items for sure.
i heard they ride rough, is that so?2002 was the first year, if it was made before April (something), 2002, it sits about an inch higher than the rest. People complained about how the handling felt, so Jeep dropped it an inch after.
It's a jeep so....i heard they ride rough, is that so?

It'd have to be damn near free for me to consider buying one with engine issues. They aren't worth very much more than that running and driving...
he has another motor that he can put in it, thats why he is considering itIt's a jeep so....

me and him both have looked at prices, and they seem to go higher than i expected.You say that, but even at auction the wrecked or mechanical failure Liberties bring more than XJs/ZJs/WJs.
The hardest part of owning one is telling your loved ones you are gay.
At least according to what @rockcity told me
Nothing useful to add

Honestly I'm in same Situation with my oldest niece 15yr old, I'm looking more into safety and reliability then what their friends or anyone else cares for that matter! I've decided my nieces jeep will either be a Zj or XJ her dream is a wrangler but not safe enough for new driver for my liking!The jeep liberty is sorta like a ford ranger, in the fact it's a coed 4x4! Who cares at 16 he should be grateful to have a ride and folks to swap engines for him!!So tell me, suitable for a 16 your old boy
