No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I always wondered this since I noticed that a lot of cars always have at least some damage to their pinch weld jack points, usually from hydraulic jacks, lack of adapters, or dropping the car onto jack stands hard. I get it not everyone has the right equipment or experience but it also seems like a poor and cheap design from the manufacturers. Why hasn't there been a method or aftermarket product that kinda bulks up the pinch welds. Hell I don't think I ever seen someone even weld or bolt on some steel to kind of guard the pinch welds from bending. Is there a reason for that, like structurally? Why are those hockey puck looking adapters the norm, just because its easier?

Tldr: Many vehicles suffer damage to their pinch weld jacking points from improper use of jacks, prompting the question of why there isn't a robust aftermarket solution or protective design from manufacturers to prevent this issue, besides those hockey puck looking adapters?

I get it not everyone has the ... experience

This is really what it boils down to. I never had this issue as a mechanic, but I didn't generally use pinch welds as a jack point. Most vehicles have numerous options for using a floor jack. You could use a control arm, or cross member, or sometimes a drivetrain component. Additionally, sometimes the pinch weld has a designated spot for jacking that seems to be reinforced.

Maybe what you are saying only applies to newer vehicles and I am out of date. Totally possible! I did not experience this 10+ years ago, tho. Only on exceptionally rusty cars that the driver would be challenged to install thr spare on the side of the road.
