Budget Lincoln MKX build

[ebodell67]

Wanted to document my low buck build on the Lincoln MKX I recently picked up. I little backstory on how I came to acquire my latest project. One of my co-workers recently bought a new Ford Maverick and just wanted the MKX gone. I half joking asked him what he wanted for it. He said $200 and it's yours. So now I am the owner of a rather well used MKX. The car has 260K miles on it and are mostly highway miles as a work commuter. He has done a lot of maintenance over the ~8 years he owned the car. New CVs, PTU, struts, etc. He also did the oil every 3K miles. So it runs and shifts just fine and the motor is clean with good compression. Of course it has some issues; AC has a leak, oil light is on, front seats no longer heat, a very loud banging from the suspension. 

 

The first thing I did was detail the entire car. I know this is backwards but I am more motivated to work on a clean vehicle. I attached a shot of the car as I brought it home and then some shots after I cleaned it up. I extracted a fair bit of dirt from the carpets but overall it cleaned up very well. There is a missing CD unit on the passengers headrest (not sure what to do here, I may 3D print a little storage box or build a wood box of some sort. 

 

I have now started the mechanical work. I changed the oil and replaced the oil pressure switch (replacement was included in the sale). The switch was a bit tight and took about an hour but after I got it in the light went out and stayed out (it would go out after the car ran for a bit so I assumed it was a bad switch). 

 

Next I took a look underneath to find the banging issue. I have the three-piece driveshaft with two carrier bearings. Both bearings are shelled out with one of them completely gone and acting as a driveshaft hoop (think NHRA rules). Driveshafts are a bit pricey but I can get the carrier bearings alone for about $50. I did a little digging and I am pretty sure I can separate the driveshaft and rebuild it. I have rebuilt several "unserviceable" components in the past (it helps to have access to a full machine shop). I hope to pull the shaft tonight and get the parts on order for the weekend. After that I will check the wheel bearings (the PO thought at least one of them was bad), then tackle the AC.

 

Overall it seems like a decent car and everything works in it aside from the front heated seats and AC (I will T/S the seats at some point if I keep the car). I am not sure if I am going to keep or flip it when I am done. I am keeping the cost low regardless. This is something I bit newer than I usually work with so the lessons it will teach me are worth the admission price. I am more of a GM guy and I think the sun rises and sets on SBCs and BBCs, but my daily driver is a '92 Grand Marquis that has been stone cold loyal. I don't know much about the MKX/Edge platform but that may change as I get further into this one. 

 

So far my costs are: 

Purchase price: $200

T&L and title: $98

Cleaning supplies (I can use these elsewhere): $24.24

Oil and filter (Supertech 5W-20 and a Napa Gold filter): $37.91

Quart of 75W-140 (for the PTU): $16.56

 

So at this point I am all in for $377. Will see where we go from here.

The appearance is really good, and the interior looks un-used.

 

You sure scored a bargain of a lifetime.

Nice looking vehicle for that many miles! Hopefully you can continue to knock out the issues for cheap and your labor, and find you like it enough to keep, but either way, keep the details flowing!

 

I junked a 2000 Grand Marquis at 330,000 miles because it just had too many little issues and it became not a pleasure to drive. I sorta regret it now as the replacements have failed to live up to expectations, and I could have tackled most of the issues in a week or so (engine still purred, transmission still was shifting fine, it was starting to guess wrong what gear it should be in).

Got the driveshaft pulled out last night. All the fasteners came apart fine (I sprayed them with Free All on Saturday). Might not be the only drivetrain problem but the carrier bearings are shelled out for sure. I will see tonight how to pull the shaft apart.

Last night I got part of the shaft separated. There is a splined connection on the center shaft that I was able to get apart. Took some heat and a deadblow but it finally broke free. Should be something similar on the opposite end but I ran out of time last night so I sprayed it with Free All and will try again tonight. At least I am making progress. Hopefully I will have it back together this weekend. I have two other automotive projects I am working on in parallel and have some chores at the farm to do so we will see.

I just replaced the front driveshaft on my wife's BMW X5.

Be sure to use a good molybdenum spline lube/grease when you re-install the driveshafts.

Thank you! I would like to think I would remember to do that but it helps to get reminded. Sometimes I get tunnel vision and neglect some of the details.

Got the other splined joint apart this week and pressed the new carrier bearings on and the shaft back together. Second joint fought me a lot more than the first one did but it finally came apart. I used a big socket and one of the old bearings to press the new carriers on. Installation was pretty straightforward as well. Took the car out for a test drive and it drives good with no vibration. There is still a rattle coming from somewhere but the loud banging is gone. Next up is the AC. I also forgot that the third brake light is not working. Took that apart (had to drill out one of the screws) and found the connection is pretty much shot. Replacements are $50 so I am just going to directly wire it in to keep the costs low (kinda the theme of this build anyway). 

 

The new carrier bearings were $50.28 delivered to my door. So that makes a grand total of ~$427 into this one to date. The AC may cost me a few $ depending upon what I find. I hope it's not the evaporator core as I do not want to tear the dash out (but I will if I have to). AC parts seem reasonable so at least that is a positive. I will get a vacuum pump on the system and put some nitrogen and dye in it to find the leak. 

 

So far the repairs have not been to crazy and it has not fought me as much as I thought. It is actually pretty clean underneath as it has not been on much gravel in it's life. 

 

About ready get it insured so I can do more than just yard drive it.

Been a couple of weeks since I have been able to work on the MkX. Over the long weekend I put a vacuum pump on the AC system and pulled it down. I was then able to inject some UV dye into it. After that I charged it with nitrogen and ran the system for a bit to circulate the dye. Unfortunately I really cannot see the connections on the compressor very well, but it looks like there is a leak at the compressor when I shine the black light in that area. I ordered an o-ring, desiccant element and expansion valve kit. I will get all of this installed and change the oil in the compressor and cross my fingers. It definitely has a leak as the vacuum drops from ~28"Hg to ~10"Hg in about an hour. Pretty much the last thing I need to take care of before it is ready for the road again. The third brake light is still out but that is an expensive part so I am going to rig up something there.

Well, this one is on hold again. Broke a ball joint on my daily driver ('94 Grand Marquis) so that needs to get fixed first. Pretty much going to have a new front end on it when I'm done. Just waiting for the rest of the parts to show up. 

Tow was covered under insurance (fortunately). Shredded the tire as well but that was replaced with my road hazard policy. I was only going about 5-10 MPH when it let go so I could limp into a parking lot.

Finally got back on the MkX. Finished the replacing the ball joints on the Grand Marquis and finally got it aligned. Pretty much a new front end under it so it should be good for 200K+ miles now. 

 

I replaced the third brake light and got that functioning now. I pulled a vacuum on the AC for about 6 hours to boil out any moisture. It pulled down just fine and after I unhooked the pump it held the vacuum for another 4+ hours. Not sure what to think now. Earlier I injected some UV die into the system and pressurized it with nitrogen. After doing that and running the system I was never able to find a leak anywhere even though it bled down some pressure. After this time I am wondering if I just did not run the pump long enough to really dry the system out. My next step is to simply replace the Schrader valves in the high and low pressure ports, pull another vacuum and if it holds, put a couple cans of R134a in it and go from there. At this point I am more or less done with the car. I just need to add it to my insurance and drive if for a bit to make sure there is nothing else. The wife wants it so I will give it to her to drive for at least the winter and see how it works out. It has great tires on it so we might as well run it for a while. The current total I have into it, before any R134a and insurance, is $493.17. So if I can get 6 months of use it will not really cost me much. The dang thing is starting to grow on me. Always starts right up with no engine or trans noise. I have not driven it much aside from on the gravel (no insurance and I am paranoid about that) but it seems to handle just fine with no vibration or whining. Will get some insurance and some drive time in it. Few little things to look at; heated seats don't work but it may be a switch and the sunroof has a tendency to drop off the tracks. Minor things that don't stop us from using it.
