I don't know your experience level, but setting up a rear end is challenging for even experienced people. If you don't get the gear pattern correct, you will have nothing but problems. There are some short cuts, but a pinion depth setting tool and dial indicator are some of the necessary tools to do it correctly.
If you are just changing it to swap the gear ratio, I would say leave it alone or pay someone. If yours is broken, I would recommend getting one out of a junkyard, rather than trying to get the tools, parts etc. You will be money ahead

2001 f150 jerks really hard when turning

You probably have a limited slip differential. Sounds like the clutch plates in the differential are sticking when you turn corners. I would change the gear oil and add limited slip diferential addative to the diff along with fresh gear oil. If limited slip this will cure your problem.

I have a ticking noise coming from what I believe to be the crankshaft angle sensor. It goes in where the distributor use to go on the right side of the engine block. Is there anything special about...

No special rules or tools to replace. If you get a used part you will need to get a spacing shim that sticks to the end to correctly space it to the flexplate. Otherwise a new one should just unbolt and go right back together.

While in drive, hear clunking and grinding from front differential and axles chatter and hardly spin, drivers side chatters,passenger side spins, put in park, then back in drive and then passenger side...

It sounds like your limited slip differential is in need of a fluid change.
The clutch packs in the axle require a special friction modifier,about 4 ounces added to the axle lube,which fixes the chattering issue.
I'd suggest someone drop the axle diff cover and check or change the
fluid,to see if there are any big metal pcs. in there. If there is no damage,drain the diff fluid and add the friction modifier,only if a SLD..

Note: Only add the friction modifier,if you have a limited slip differential.
Since I can't physically see your vehicle,make sure a mechanic does
it right.

1996 jeep cherokee laredo front differential is broke what do i do to fix and how hard is it. should i replace the whole axle unit or just the differential

If you can get hold of the complete front diff housing,including all the brakes etc,it is a lot easier to do the change.On the other hand,if you have a good workshop and know the steps to take,replacing just the diff centre is a bit cheaper.By a good workshop I mean,hoist,air tools good lighting etc.Both jobs require approx.3hours and a good helper makes the job a lot easier.Without a good workshop I would go with replacing the entire unit.Make sure the brakes are in good condition clean and all the air bled out of the system.Replace the diff oil using l/s diff oil.Hope this helps

Hello,this is Nick...i've got a 1990 bmw 3 series

yes there are many companies that sell window kits to convert the car, as far as the diff noise goes u need a load of special tools to do this repair, by the time u buy all the tools to set the gears up correctly u could pay someone to do it. Do you still want to do the diff gear set?

Turbo 2ooo i think it might be some sort off bushes

juddering is UK english for shuddering in US english. The center bearing shouldn't move, i/e/ the shaft should rotate w/o side play in the bearing, but the rubber mounts for the bearing should be flexible. The needle bearings in the universal joints in the front to rear drive shaft can go bad, causing noise when accelerating and they're not changeable w/o special tools. Your problem also sounds like differential, which would mean that you need to change the gear oil in the rear differential. As the oil ages it stops working properly in the limited slip differential even if visually OK. Do the front differential at the same time, engine heat ages it even faster. The center diff is in the AT, so you would change the AT filter and fluid.
How to tell which problem you have... in a parking lot with dry pavement, stop the vehicle, turn the wheel hard right, accelerate a moment, and repeat hard left and centered. If its worse turning, than straight suspect the differential fluids first. If its the same turning or not and especially if its the same on wet or dry pavement and at slow and high speed then look into the propeller shaft first.
