Starter motor Denso or Bosch

Bosch is just fine. I replaced my starter with a Bosch reman a few years ago, still working flawlessly.

I finally had to replace my OE starter on my 2nd gen at \~230k miles. The OEM Denso starters that Toyota uses on these trucks are solid. You are more than likely fine for a long time.

Denso starter in my Toyota 4runner lasts like 15 years / 150k+ miles before needing a rebuild and can take it out easily.

This is 100% your starter motor. The solenoid isn't pulling the starter motor gear off the flywheel fast enough so it grinds. Gets worse in colder weather. The fix is a new starter motor

Bosch has been just fine for me. I also had to replace my starter, go with a brand new bosch unit and youll be fine for a loooong time. Cant beat OE quality.

Might be a long shot but see if there is a Starter/Alternator repair shop nearby. They will be able to disassemble and fix what is wrong using much higher quality parts that what auto parts stores use.

I went with Denso from Advanced Auto last year. So far no issues and very nice quick starts

It killed what is left of my soul but I mickey moused it. All the starters that match at the parts stores (bosch, ac delco etc) lack the correct plug. Used a couple ugly .250" flat connectors. how embarassing.

About 2 weeks ago my bike started to struggle starting when the bike was hot. It acted like the battery was dead - which was a fairly new (3months) old) Lithium Ion Shorai Battery. I replaced the LiOn with the OEM battery (that's $500 in battery's and a LiOn charger). After much research online it seems this is a known issue with the Denso factory starter motor. The brushes wear unevenly, and quickly.

My wife's '06 Range Rover Sport suddenly wouldn't start, just a loud clack, sounds like coming from the starter solenoid. I've worked my way to the starter, I'm thinking it's a bad connection to starter, solenoid contacts, maybe even the starter.
