I forgot about those.


I changed mine at 230,000ish. They had the stockers on them. When I took the old ones off, they were just as tight as the new ones I put on. It made ABSOLUTELY NO DIFFERENCE at all. But I have seen worn out shocks before, so I guess I just lucked out with a good factory set!

I saw a Huge difference in handling when I changed my upper and lower A-Arm joints. They were completely shot.

 

Bilsteins all around on mine as well. No problems. Lifetime warranty even if you did have a problem. My stockers were dead at less than 40K. Could compress them by hand and they did not return to correct position. Stockers are junk unless you had the upgraded "Rancho" series.

 

what shocks came in the 08 KR's? bilsteins right?

 

So one thing I have noticed is that my truck uses a lot of oil between changes. It's not burning oil, it's not leaking oil, but after 1500 miles or so I'd say I'm a quart low. I'm using Mobile 1 5w30, any thoughts? I thought it might have something to do with my exhaust (straight pipes - not true dual, just no muffler).

 

Fram or other PCV valves can effect oil consumption. To much restriction in their valves. Make sure your running a Motorcraft valve. Keep in mind, -ANYTHING Fram can very easily destroy these engines or hurt it.

Motorcraft and Castrol are at the top as far as oil IMO.

 

A lot of good information has been posted here, and I'm not going to rehash it all except for this one little item...the PCV valve.

The books recomend changing the PCV at 100k. I didn't change mine, and it failed at around 120k. My oil usage went from very, very low, to very, very high within just a few days, while on a 4800 mile two week vacation. To make a short story long, I checked the oil a couple of days into the trip and all was good. Checked it again about a week/2000 miles later, and it didn't show on the dipstick...it was almost 4 quarts low We limped the 1800 miles back home pouring oil through it. Once back home, I was ready to grit my teeth and take it in to a shop, expecting major engine repairs. Just before I did, someone suggested trying a new PCV valve. Changed the valve with a Motorcraft part, and all was good again. Now at 158k and oil consumption is still very low.

I never lost pressure as indicated by the idiot gauge, so I don't think I did permanent harm to anything, but it was probably scary close.

 

Thanks for the tips guys, I changed my PCV valve about 15000k ago, but it sounds like it might be worth doing again.

 

Chester you must have some kind of magical truck. Most of the things you mentioned need to be change much more frequently then you mentioned. Shocks for example... I've never heard of stock shocks lasting over 100k miles and you say yours were still good at 230K? Also.. never changed your fuel filter until 230k? I change mine ever 30k and find that amazing that yours would last that long. Never changed your brake or steering fluid? Again amazing because most trucks need this every 40k-60k. Maybe somebody is servicing your vehicle without you knowing it?

 

Chester...I've got to rag on ya a little... all in good fun though!! You must have no nerve endings anywhere in your body. You have got to be the numbest person on the planet. There is no way on god's green earth you changed stock shocks out at 230K miles and couldn't tell a difference. Ditto for the brake fluid and power steering fluid!

I changed my power steering fluid out at 80K and it made a HUGE difference. Same for the brake fluid that gets completely flushed out with every brake change or two years! Yes, many things you never feel in the "seat of the pants" (transfer case fluid, front/rear gear oil, antifreeze, etc) but that's not true for most others. You crack me up, but best of luck to ya!

BTW, glc and these other guys don't know what the hell they're talkign about...You want Amsoil for all your fluid needs...Tranny (ATF), 0W20 for the engine, ATF for the steering, BF3 (DOT 3 Fluid) for the brakes, EVERYTHING!!!

 

Thanks allot, I'm switching to Wolf Head now

 

No they don't. Some people just do it anyway cause they read on a board somewhere that it will break their truck if they don't. I'm telling you that you don't have to, and it makes no difference(except in your wallet) if you do. If it gives you peace of mind, then whatever. Can't put a price on that.
You've spent a lot of money on things that are fine if left alone. Look in the owner's manual. How many times does it say to changet the power steering fluid, or brake fluid, or rear axle fluid etc? It says to NEVER change them, cause hydraulic fluid doesn't wear out. (not in a reasonable lifespan anyway)

You can put "space shuttle" oil in your engine, and change it every 5 miles, and it still isn't gonna be doing any better than my engine does at 300,000 miles! And that's the thing that helps me tolerate the ridecule.

All I'm saying is that you don't have to do all of that crazy maintenance.

Best of luck to you too.

 

That is the WORST stuff you can use - that is the grade of standard Mobil 1 that has a formulation problem which is causing excessive wear in OHC engines. If you want to use Mobil 1, use the 5W20 EP.

 

I totally disagree with you, brake fluid over time becomes contaminated through condensation, which in turn can damage ABS sensors....perhaps your truck is not ABS equiped.....It says in the manual to even change the rear end fluid at 100K intervals if used heavy, which for most of us who live in temperature changes, & towing things!......However your truck is the one running with 300K miles, so I won't argue with you!.......

 

Well, time will tell I guess. I've been wrong before. I'll let you know if and when it breaks.

I will say this: 300,000miles is alot. Too many if you ask me.

 

I bet your shocks are Green and Yellow
