Is it necessary to have the wheels of a car aligned with the body when parked, due to weight on the axle?

My uncle says a driver advised him that whenever the car is parked, the wheels have to be aligned with the body of the car, or else there will be un-necessary weight on (I think) the axle or wheel, which reduces the life of the parts. So is it…

Are there different greases for inner and outer CV joints?

I was watching a video by Eric the Car Guy on changing a CV boot. In it he mentioned that there are two different types of grease, for inner and outer CV joints, which can be identified by the colour of the grease. According to him "inner joint…

Why don't FWD cars have rear differentials?

This confuses me. The point of a differential is to make it so the wheels don't slip when one needs to be turning faster than the other, such as during turns. So if the rear wheels are directly connected by a solid axle, doesn't that force them to…

Torque wrench or impact gun on large bolts

For very large bolts (example: axle nut) I often see mechanics just use an impact wrench, typically they let it "rattle" a certain time and then they consider the bolt tightened. Is this also common/considered acceptable practice in other…

Alignment is out of spec a tad - should I worry?

So I bought new tires recently for my 2002 Nissan Sentra and wanted to make sure that my alignment would not eat them up. Even though effectively my entire suspension/axle system was overhauled recently, some of the specs are still off. Three…

Bad CV joint, but which side?

Honda Accord EX 1990, just bought. When I make a tight turn, I sometimes hear a rhythmic clunking sound. This is supposed to be a tell-tale sign of a worn CV joint. But how do I know which side it's on? When I had the front wheels off, I inspected…

Best Way to Clean CV Joints of Old Grease

I'll be replacing the CV boots on my axles pretty soon and was wondering what the best way to clean the old grease off is. Are there any common solvents that would be useful, or are just a bunch of old throw away rags all I need? I'd like to do it…

Are rear rigid axles repairable? If so, how?

So basically I had a t-bone accident (I was hit on the side) and as a result of the crash the rear wheel on the driver-side is now tilted inwards (kind of like it had negative camber) and a little bit to the left. The problem is that when I see…

Why is my drive axle clunking when I first accelerate or release the pedal?

I recently replaced my drive axles and my passenger side clunks when I first accelerate or decelerate. It also clunks when I let it coast at a low speed. Pushing on my brake stops it. I'm thinking it can be two things. It's possible that I didn't…

Can't remove stuck rear dirt bike axle

I'm trying to remove the rear wheel on my 2007 Suzuki RMZ450. I've removed the axle bolt and tried banging the axle with a rubber mallet for about two weeks now. IT WON'T BUDGE. Not even a little bit. It seems to be completely seized up. What can I…

Why do multi-axle vehicles have "innie" and "outie" wheel hubs?

Observe these multi-axled vehicles: See how their wheels are either "innie" (stick inwards) or "outies" (prodtrude outwards). Why is this? I note that in 3-axle (6-wheel) vehicles in particular, such as the third picture below, it's often the 2nd…

How Much Grease to Put into the CV joint?

I'll be replacing my CV boots soon and was planning to clean out all the old grease and put in new grease. Should I pack the whole thing full of grease, including the boot, or is just packing the joint / bearing itself sufficient?
