$340 to do the coil packs and spark plugs

[cranbiz]

An hour and a half is pretty much what it takes me to do the plugs on a Pentastar. I can actually do my JK faster as I slightly modified a couple of the PITA brackets (because I was blowing #2 coil packs due to an intermittent short). On my 2017 WK2 it's a full 90 minutes. I suspect the Gladiator will also be 90 minutes but I don't need to cross that bridge for awhile. 8mm and 10mm sockets and a few wobble extensions are the primary tools needed.

I've never owned "wobble extensions" - just flex sockets. I wonder if there's an advantage to those extensions vs. the flex sockets - which eventually loosen up and require an application of a wind of duct tape on them to keep them from flopping around........

Some of the best money I've spent on the tool truck outside of the turbo sockets

The guy who did mine used a wobble extension on the passenger back one, he said it's the only one you really got to use one on. I have no experience to say if it works better or not but YouTube guys I saw doing it used one in the same spot so I'm assuming there is a advantage.

Hey for reference Id like to throw this in. So pulling back from Charleston SC when we bought the Camper we averaged around 9.6 MPGs mostly interstate driving at around 62 average mph I'd have to guess but we had no real stops other than for gas the one time. That was with a 6046lb camper behind me, our previous camper was 4086lbs and I got 10.8 on our only trip in it to Myrtle beach. All on 37's. This trip to Myrtle after the tune up and running into heavy traffic on Kings HWY we averaged 11.1 mpg on 37's. I got the 33's in the garage but decided I wanted to see if the tune up made any difference and obviously it had to. I gained mpg and pulled a heavier camper. I'm really curious now to see what it will do on the 33's plus oil temp never got about 242 and transmission temps never above 217.

That's the bolt you really need it for. Any place where you can't get on the head straight is a use for a wobble extension. I use the crap out of mine.

Without a hinged extension, you can’t get to that one.

After reading this I went out and hugged my wifes TJ. I like doing tune ups on the 4.0. I will pay someone to do my JT. I have a F250 V10 tuned it the first time, 1 1/2 hours for 9 plugs. 4 hours for the one under the AC at the firewall. Next time it needed plugs I gladly paid to have it done.

Yeah I don't blame you. It was 45 minutes to an hour to do the JKU I had on the 3.8. I was more than happy paying someone to do mine on the JT

My thoughts are that if it sucks as much as it does to do it carefully and well, no one you pay will likely give a shit. They’ll just turn it to get it out of their bay. I’ll keep doing it myself.

I dunno - local dealer had to pull things apart to replace the spark plugs in our 2021 Grand Cherokee with 800 miles on it.
Zero issues - no leaks, no mess, no oil spills. Under the hood was clean and proper.
Never had another problem with it.
It was a warranty issue to boot - so they were getting absolutely Jeep's numbers on it.

I guess it depends on where you live and what shops you use.

I’m guessing that the larger the population, the worse work.

I could see your point there as well. The dude I got to do it was highly recommended and appeared to care a great deal about taking care of it, was very professional. I'd definitely get him to do other things mechanical if I need something else done.

LOL - that could be??

Shops are like any business, even a franchise eatery.......... all it takes is one or two not up to snuff and the whole place suffers.
You can eat at the finest restaurant in the world and find out the guy has a second location in another town - you go there and the food sucks.

It's like my examples - the spark plug replacement was perfect.
But the same shop is the place that told me my winch was draining my batteries and they fixed it by moving the ground cable from the top of the IBS over to a fender ground. Electrically the same (save for some voltage drop at the fender ground)
Same shop - had good results there for years. Different tech, different day.
(that shop is suffering now after covid as they can't get qualified people hired - so I go across town)

Yeah. I’d definitely never ground a winch anywhere but directly to the battery.
