Trying to extend the life

I am trying to extend the life of my '98 12V 4wd quad cab. I have about 160k on it. I have rebuilt the front axle and am currently rebuilding the rear, as I have a lot of play in the pinion. Also done the ktab mod, and pretty much just changed oil and filters regularly. Oh, also a transmission rebuild about 20k back. Also front wheel bearings. Any suggestions as to how to extend the life of the truck would be helpful.

Welcome,
I suggest reading the beginner's threads/stickies....learn about the truck then ask detailed questions....
I'm similar to what you are asking...longevity and efficiency are what drive my decisions....

Nothing to it. Perform scheduled maintenance. Fix every little thing that quits working asap rather than letting them add up to fix "one of these days".

One thing I would advise is get a good dash cover and a windshield sun cover. Use it . My dash and the structure is shot. Big bucks and a pain to fix.

160k is not even broken in yet!! Only half-kidding on that, but these engines will pretty well run forever - I've got just under 400k on mine and there are a few million-milers around here. The life of a lot of the rubber/plastic tends to be a function of years, rather than miles, though, so there's some parts (intercooler boots, front/rear seals, vacuum and heater hoses come to mind offhand) that probably could do with an inspection or just a pre-emptive replacement. 160k seems very early for axle rebuilds, but I don't know the 4WD setup well.

Good additional info.

To add to that, there are dozens of posts and threads on the forum about good and bad products. Rather than beat a dead horse I urge the OP to do some research.

Yup, 160 seems too soon, but I did quite a bit of hauling loads for a couple years, 10lb sailboats north to south and back on the west coast, and 4 trips across the country hauling a loaded 20 ft shipping container on a trailer. The loads finally caught up with me. I wish I had the dana 80 instead of the 70u. Sounds like they are more durable.
