So I‘ve always done a bunch of my own repairs. I‘m doing the front wheel bearings (the assemblies with new rotors and brake pads) on my 2004 Explorer and I just had someone tell me that I‘m supposed to get a front end alignment when I do bearings. I‘ve never gotten an alignment after doing bearings in the past. Is an alignment needed?
Anytime a suspension system is disturbed, an alignment is always recommended. Having one done to make sure things are in spec is a lot cheaper then replacing tires with wear caused by camber and toe wear.
The tire manufacturer and the truck manufacturer both recommend tire pressures. The tire manufacturer will have it printed on the side wall, while the truck manufacturer will have it printed on the inside of the drivers door pillar or just refer to the owners manual.As long as you are going with the size tire that the truck manufacturer recommends,use the tire pressure that they print.That tire that they recommend is also the tire that corresponds to the allowable weight that the truck will haul.If you are using a tire other than the truck manufacturer allows,use the pressure printed on the tire.
If what you load affects the inner pressure of your tires, then the tires on your truck are likely not rated for the kind of load you are hauling, meaning you probably need a higher load rated tire because what you're doing could result in a blowout. I am not sure what kind of truck you have, but on my D-2500 3/4 ton pickup truck I have the kind of tires that require 50psi per tire, and they make even heavier duty tires that require 80 psi per each, and so on. As a rule, 4 tires for my ride cost $500 for starters, and from the sound of things you have car tires on yours, and you need truck tires.
Its not required, that someone doesnt know what they are talking about. But doing one as maintenance is never a bad idea
Lower pressure - 70 PSI is unacceptable, and it's only a matter of time before the tire explodes.
