Have you checked your ball joints and control arm bushings? Is the front end tight? A bad ball joint or contol arm bushing can cause shaking when the brake pedal is applied. Also can be a sticking caliper, rust under rotor hub. Is it pulling at all? Sticking caliper, twisted brake line...can cause issues as well. This is assuming your Autozone rotors are not out of round. If the front end is tight, I would try a different brand of rotors.

I would be careful buying a used abs module because it may not code to your car correctly. Might even throw other codes. Need to be matched to your ECM in some cases.

Some of the equinoxs came with factory installed block heaters in the oil pan and plug in the front grill. If it didn't, I'm not sure you can install a factory setup without replacing the oil pan. You can try the magnetic from Katz or one on Amazon:

Where did you buy the battery? If you got the wrong size, most retailers will let you exchange if not installed. They should have looked up the correct battery...Autozone, Advance, O'Reilly, Napa, etc.

Did you find the leak? That code is for a small evap leak.

Do a fuel injector balance test with a scanner, you may have a bad injector. Also might be a good idea to do a compression test.

1999 Ford Ranger should have a rack and pinion,so no steering knuckle https://www.oemfordpart.com/v-1999-ford-ranger--xlt--3-0l-v6-gas/steering--steering-gear-and-linkage Are you looking for the steering column shaft?

Have you checked ebay? https://www.ebay.co.uk/b/bn_7012519101 Do you have a part #?

I'm familiar with Raybestos brakes 😃

Advance owns worldpac and worldpac has more OE lookup than aftermarket available in their catalog.

O'reilly as an example, does 90 days on the replaced item: https://www.oreillyauto.com/warranty If a product is replaced under this warranty (“Defective Product”), a replacement product will be covered for 90 days from the date of exchange, or for the remainder of the warranty period, whichever is greater. This warranty for installed vehicle parts shall terminate immediately if you sell or otherwise transfer ownership of the vehicle that had the defective product installed, or if you install or use the replacement product on another vehicle. Autozone same: https://www.autozone.com/lp/termsAndConditions#autoZone'sLimitedWarranty AutoZone's Limited Warranty If a part fails during the warranty period shown on your receipt, bring the part to an AutoZone store and you will receive a replacement or refund. Warranty excludes damage caused by misuse, abuse, other faulty parts, improper installation or off-road, commercial or marine use. Warranties on replacement parts cover the unused portion of the original warranty or 90 days, whichever is longer. Warranties expire when you sell your vehicle.

That's pretty much everywhere. Warranty starts from the original purchase date, even with replacements. See https://www.rockauto.com/docs/warranty Check out this part: We hope the warranty summaries below will help you in your purchase decision. Please be aware that: Like other retailers of branded products, RockAuto does not offer any product warranty of our own--we honor the warranty provided by the manufacturer of the product. If you have a problem with a part during the warranty period, please submit a warranty claim through our Order Status & Returns page. The summary below does not include all the terms and limitations of each manufacturer's warranty, and manufacturers may change their warranty terms without notice (to you or to us). For warranty details, please visit the manufacturer's website. Warranties apply only to the original purchaser of the part, and to the vehicle for which it was listed in our catalog and on which the part was originally installed. Terms listed apply only for parts used on a private passenger vehicle; warranties for cargo, commercial or off-road vehicles may be more limited. Warranties offer only replacement of the defective part with another part: no cash refunds and no reimbursement of labor costs, shipping costs or other expenses. Replacement under warranty does not extend the warranty term. Warranties begin upon delivery. Wholesaler Closeout items have a 30 day warranty (but still are covered by our Return Policy). This is where a local parts store that may be a bit more expensive, maye have taken care of you and defected out the bearing.

My guess would be early 70's VW bug rear bumper or some other smaller car from the 70's.

You might be better off when you park your car just place a box or some object there if you are concerned about access with a stick and a break in.

Were you able to identify what these are? I took a stab at it, but no idea. Looks like a 90's pickup rear light assembly
