I drive it everyday.

Surprised they had the filter in stock at Walmart.

Did oil and filter yesterday too and learned that the boots on both upper balljoints are blown tf out. They looked fine in April when I did front brakes.

At least now I don't feel so bad I didn't get an alignment back when I should have. Could probably just replace boots because there doesn't seem to be any wear. Assume this is because It Never Rains In Southern California, so the grease never got washed out and prevented dirt from getting into the joint. Nevertheless, I ordered TRW balljoints and Moog swaybar endlinks w/ poly bushings. Should be changing tomorrow evening so long as nothing gets in the way.

That reminds me of something I learned yesterday from an engineer who works at a plant that manufactures bearings and seals.

When lubricating joints with a grease zerk, never grease it until the grease starts to come out. Apparently, doing that weakens the grease seal and allows foreign contaminates (dirt) to enter the areas - which is the #1 cause of bearing failure.

So, never grease a joint until grease starts to come out.

Who knew?

[stir_pot] That's like saying "Don't break wind, or you might get underwear lint in your butt hole, which is the leading cause of male cervical cancer."

But seriously, the seal is essentially like a check valve. Grease can push it open and escape, but once it does, the seal closes again. How do contaminates get in past escaping grease? That would be like getting into an elevator while the others are still getting out. [/stir_pot]

Yep. Took 1 tank to get there and another to get back. The majority of the drive was at 70-80mph, so my average MPG was about 13.

What a concise and well argued point!

Just upper. God damn balljoint sounded like a loud ass firecracker when it let loose, and the boot looked like the LOL WUT pear. Other side was worse.



Lowers were fine. Everything looks good for now. Didn't do even a crude measurement, but the front wheels appear to have less camber now for some reason. There was no play in the old ball joints. Maybe I'm imagining shit. Need alignment now either way.



Also painted the A-pillar trim because the Pathfinder tweeter panels are darker than what came in my truck. Duplicolor vinyl&fabric dye is a good color match. Have had very good results with this product over the years and it's about half the price of SEM.



And installed Euro ATC fuses because they look cool and can see if they're burnt without having to remove them.
