Just looking for some advice from you guys experience.
Just helped my stepson buy a clean 2007 Frontier, 4x4, ext. cab, 4.0 with 142K miles for $9,500. Seemed like a good deal and then the problems started.
1st Week - I knew there was a vibration in the tires. Went to Discount Tire and they showed me that the entire set of tires were from 2001. I didn't expect them to be older than the truck. One was coming apart from the inside. $800 later, problem solved.
2nd Week - Check Engine light. Replaced 1 coil pack and all spark plugs. $120, problem solved. Runs much smoother.
3rd Week - Check Engine light. Needs new cats. The top two broke up and clogged the two downstream. $2,100 later, problem solved.
The very next day....super loud squeaking. Narrowed it down to the front u-joint on the rear driveshaft. Replaced both of them for $30.
So in the past month I've spent over $3,000 on this truck that I thought was a good deal. Not to mention I gave him $2,000 to put down on it.

What else should we keep an eye out for? Hoping this fixes all of the common issues at this mileage.

Thanks for any input.

Radiator/transmission contamination if it is an automatic. Engine mounts if taken off road.

It will take more than that.Do a search on radiator cross contamination. People here can explain the problem better than myself. I drive a six speed.

I have an auto, i bypassed the radiator by switching a transmission line. Then i added an auxilary trans cooler for about 60 bucks. Info can be found all over this forum as well as thenewx.com.

Another common problem is the timing chain. The tensioners and guides use plastic shoes that become worn over time. The engine creates a noticable whine noise when this occurs.

Look on youtube for an xterra bypass how to and look online for timing chain noise.

Otherwise these trucks are very dependable. Basic maintenance should keep it runnin well. Good luck!

coolant system contamination a problem with age? or is it something i should look into addressing now? 2012 with 43k v6 auto
General consensus on the forums is that this problem was fixed after 2010. But a 60 dollar part and switching two hoses is worthy of avoiding a potential 5500 dollar repair in my perspective.
