Doing the recommended 90k maintenance this weekend, truck is an 05 with 93k miles, also doing the rear axle fluid change, coolant flush, and installing diesel site coolant filter, any tips or other recommendations would be great.

 

You should be on the third tranny fluid and filter (extrenal) change.

I have heard that this is about the point at which the brake pads wear out, the ball joints begin to fail, and the serpentine belt is worn out.

Many say that you should do your second brake fluid flush also, but I am at 60k and haven't done one yet - I guess I am a slacker!

Edit -

Oh yeah, I pull the batteries and give them a charge and then load test them at least once a year.

 

got new batteries about 4 months ago, new brake pads and rotors resurfaced 10k miles ago

 

Not sure what the serpentine belt is.......

 

That is just the term for the "single belt" design for driving the accessories (alternator, powersteering, etc).

 

Ok thought so, had a new altenator and belt put on 7k ago, umm quick question, when i first start the truck, i turn the wheel and theres no power steering, but only for a quick second then its fine, would a power steering flush clear that up?

 

Possibly - or maybe the tensioner pulley is getting weak??

 

Thanks ill check it out

 

And while your under the truck you mind as well do a fluid change on the transfer case.

 

change the transfer case fluid, front and back differential fluid, steering fluid, flush coolant.

 

Dont mean to hijack the thread but my truck has approx 63K miles on it and I bought it used with approx 50K miles. Since Ive owned the truck the only maintenance I have done is oil changes and fuel filters.

Is there any sort of preventative maintenance that you guys recommend I should be doing in the near future?

 

Coolant Flush/Change.

 

05' 6.0L PS 4X4 with 105K mi

Grease your ball joints, O yea there's no fittings, then pray that they were greased at the factory to begin with.

Check to make sure your transfer case relay box was mounted right side up, mine was upside down from the factory and water getting in caused relays to go bad.

Check to make sure the the AC return line is NOT rubbing on the glow plug controller fins (on front right valve cover). Mine was rubbing , caused leak in AC hose at 95K miles, new redesigned hose was released to solve problem (now about 2" between glow plug controller and hose).

If it hasn't been done already, I would add, clean the EGR valve. Last year at 89K miles when it was -34 F the turbo started doing some strange stuff until it warmed up, then after that it settled down. Cleaned the EGR and problem went away.

I have followed the owners manual for recommended service intervals, other then oil changes at 5K miles and the EGR cleaning and coolant flush which appears to need attention sooner (60k). Now have 105K on the clock and things seem to be in good shape. But then again the little woman drives it like she stole it.

 

Follows is my maintenance schedule:

Grease Front Axle Shaft U-Joint - every 15,000 miles

Clean EGR Valve - every 25,000 miles

Change Automatic Transmission Fluid & External Filter (Change Internal Filter Every Other Fluid Change) - every 30,000 miles

Change Engine Oil & Filter - every 5,000 miles

Rotate & Balance Tires - every 10,000 miles

Change Fuel Filters - every 15,000 miles

Change Coolant - every 50,000 miles

Change Front Differential Oil - every 60,000

Change Rear Differential Oil - every 60,000

Change Transfer Case Fluid - every 60,000 miles

Change Coolant Filter - every year

Change Accessory Belt - every 4 years

Change Brake Fluid - every year

Change Power Steering Fluid - every year

 

tires are due for rotation, do you do it yourself?
