tl;dr: You can use a spade or similar tool in order to dig the snow out of the way. What are some methods I can employ to make it easier to get unstuck in snow? Having said that, there are several things that you can do or might want to consider if you are stuck in snow. How to Get a Car Out of Snow Check the Exhaust - Clear any snow that is covering ...

There is no such thing as "absolutely, perfectly, 100% safe." Each tool has its proper and improper uses, and each works either in parallel with other tools to increase safety and dependability, or in series with other tools ultimately reducing safety and reliability. Will a hydraulic jack hold up a car safely? That depends on the level of risk you're ...

Sometimes you want to measure breakaway torque. This can tell you if a fastener has started to loosen due to vibration, or was over-torqued and the bolt/stud may have stretched or weakened, or the fastener was cross-threaded and need to be replaced. Note that breakaway torque values will often be higher than the stated torque spec, as the breakaway torque ...

TL DR: Nope, I'd say not. When I was a young man, my Dad always told me, "Use the tool which is designed for the job." For instance, if you are trying to remove a bolt out of your suspension holding an A-Arm, you wouldn't use a body hammer to move it out, you'd use something with a little more heft, like a 5lb sledge or something similar. I'm sure if you ...

Aside from what you mentioned, I always carry: Portable air compressor (12v) Small tool set (common wrenches, screwdriver, grips, electrical tape and zip ties). A good flashlight Spare cellphone charger (both DC and AC if car does not have USB plug) List with emergency contacts in glove box. Rope in case I need to be removed from a ditch or towed (happens ...

To answer your question directly, this is a "standard practice" but a VERY poor one. Getting the correct torque is by far more important than getting it done quickly. With the axle nut it is imperative you tighten it to the correct spec. If you tighten it too tight, the wheel bearing will self destruct within a few hundred miles. Using an impact gun can ...

I'm going to answer the basic mechanical points, as weighted by my opinion of importance. I'm leaving out the issue of waxing as potentially too broad. Safety: These are critical. Do not proceed down the list without addressing each (at least). Safety glasses: Always wear them, especially when you don't think that you need to. I purchased mine from the ...

The main things I've always heard/done. Always unwind before storing. This helps to keep stress off the springs. If you leave it wound up, the springs can get weak and give inaccurate torque readings. Don't go past the click. Once it clicks, don't turn it further. Can't remember why you shouldn't do this (aside from over-torquing). I always try to ...

If that would be possible, every 3-year old could fasten the bolt. He just has to try 100 times with 0.5lb-ft. You have to apply the full 50lb-ft, regardless of the torque applied before!

No, I thought it could as well. One time I had a Corolla up in the air while I battled with a speedometer cable (which meant I was going in from the top of the car, underneath, and through the wheel arch). I walked away from the car to get a spanner, I came back and I was looking at where to remove a bolt. I then noticed the car was very low down. The jack ...

A hand winch and a tow strap. You need something to attach it to (a tow hook on your car and something sturdy in the surrounding area) but it's about 90 percent as good as calling a tow truck. The winch does all the work, the strap just extends its reach to the nearest sturdy object. If pulling the car six feet doesn't unstick it, just put the car back in ...

Duct Tape. Of course. Take a piece of duct tape and tape it to the lip of the ramp. Run it out 12 inches/30cm and then fold it over and run it back to the ramp. Stick this on the backside of the ramp. As you roll up on the ramp, the tape will be trapped underneath your tire and the ramp will be unable to slide away.

To my knowledge the difference is down to the material used Impact sockets look black because the surface is carbonized (aka drop-forged) in order to harden the surface. The surface-hardening enables impact sockets to absorb sudden torque changes (aka "impact") better. With high enough impact, a regular socket may warp out of shape because the steel used ...

There are many leak down testers on the market. You can actually make your own with some hardware store parts and a fish tank. Operation of "most" leak down testers The procedure of operation depends on whether or not you have the cylinder head attached to the engine block or not. If the head is attached, your leak down tester should have an attachment ...

No, it won't reduce the torque. Torque is equivalent to radius x force. As long as A, the force is applied at the same distance from the nut/bolt that you're tightening and B, it's applied in the same direction then you'll be applying the same torque. An adapter (especially so short) shouldn't have a noticeable effect on the direction that you're applying ...

I use two part spring compressors like you show here on a regular basis.* I think you'll be fine but there are some good things to watch out for. Watch out for the threads. If the compressing clamps jump threads, the spring could suddenly express a lot of its potential energy. With McPherson struts, it's entirely possible to catch a finger between the ...

NO, and I don’t understand why you don’t refer to standard workshop practise which is to lift the vehicle and then put proper stands under it. Sadly there are too many accidents of either vehicles or tipper trailers falling due to the failure of hydraulics and injuring or killing people. Don’t rely on hydraulics to keep the mass in the air: stands or ...

First off, everything Bob said. General Socket Extensions: Your socket set may come with 1 or 2 extensions but I'd buy a couple more. Having different length extensions are invaluable for getting to hard to reach items, plus you can combine them together for a longer extension. Socket U-Joint Adapter: I never see these in socket sets and you will regret ...

Basic Functionality Image In order to illustrate a typical Multimeter The Multimeter is specifically a multifunction tool. By definition it combines several, well defined instruments and multiplexes the controls for simplicity. Inputs Majority of Multimeters will have 3 input terminals. Typically you will only use COM and V/mA/Ohm input (often Black and ...

Threaded Inserts in your concrete I have placed various threaded interference inserts in my garage/shop floor. I've put them in locations where they will be useful to tie down a motorcycle or to have a bolt just sticking out of the cement to prevent something like this from sliding. I've used various diameters of insert. I can use them for a variety of ...

That would be correct. There should be no issue of using the impact with the wheel off the ground. You are exactly right in that the tire should be on the ground when using a breaker bar or tire iron. The reason for this, besides the wheel spinning and you never getting the lug loosened, is because you could torque the car over and cause it to fall off of ...

Neither. Just get a 1m long bar (by extending a breaker or similar), stick it on the nut so that it is horizontal and simply hang 250N of mass at the end of it: (*) 250N = 56.2 lbs = 25.5 Kg 250N * 1m = 250Nm Rinse and repeat until it hangs and doesn't tighten the nut anymore. The trick is to keep the bar horizontal, you'll likely need a 12-point socket ...

There are sockets designed specifically for this job. Here is an example of one; they have a reverse thread on them and are made of hardened material so as you turn them anti-clockwise, they tighten themselves over the locked wheel nut until they are fully tight and the nut begins to loosen. They are made by most tool manufacturers and available from most ...

To be a little more pragmatic than the other suggestions... what classifies as an emergency can be subjective. To me the emergencies I have experienced in a motor vehicle typically come in the form of flat/blown tire or running out of gas. Because of those experiences I keep the following in my car at all times: Tire Changes Small Sledge Hammer- if you ...

"Torx" is a trademark, i.e. a name for a company and can be renewed indefinitely. The Torx design used to have a patent that expired in 1990. After the Torx patent expired, ISO 10664 was created that described the Torx design. "Torx Plus" is also a trademark. The Torx Plus design was developed to handle more torque and that design is under a patent ...

Torque wrenches are used for adjusting the specific tightness of nuts and bolts. They come with an adjustable torque setting which is usually in foot pounds (english) or Newton meters (metric). In automotive applications, most nuts/bolts will have a torque setting specified in the manual that when applied will give the exact amount of pressure needed to ...

1. How do I operate a leak down tester? Directions differ depending on whether it's a one gage or two gage system. It basically gets down pulling a spark plug, getting that piston to Top Dead Center (TDC), threading the tester into the spark plug hole, hooking up compressed air (at a minimum pressure), bringing the cylinder pressure up to a set amount, and ...

Being as it's only 0.05mm larger in diameter, you shouldn't have a problem unless you're using that socket on a rattle-gun every day. If it's a 6-point socket, the wear on the nut should be minimal (12-point sockets have more of a chance at 'rounding' the nut). Ideally, however, you should go down to the shop and spend two dollars on the correct sized ...

This is a good recommendation The wood will compress a bit when you lower your car down onto it. The jack stand will dig into the wood as well. The benefits related to this related to the vehicle slipping on the jack stands. I've never had a piece of wood fail doing this, although soft white pine sometimes comes out looking pretty beat up.
