SOURCE: need instructions for removal and installation of

If you have never done it before, It would be best to just remove the shaft and watch how the joint is removed and installed, by a mechanic. You can avoid damaging the new u=joint or bending the yoke. Then your problems begin. Let someone show you the how on the first one and it will be a cakewalk thereafter. Good luck.and be safe. Make sure the driveshaft has no load or pressure on it before loosening any bolts.._Ned_

SOURCE: I need to replace the transmission mount on a '94

Supporting the transmission while removing the cross-member is easier. You will have the engine mount holding the whole thing in precise place, while you deal with the crossmember, and the transmission.

Comparing: if you release the engine mount bolts and jack up the drive-train, the whole thing would shift, and you could have trouble when the cross-member fails to go up well enough.

On the other hand, if the cross-member bolts fail to release due to "home-mechanic" syndrome, you have only the first option.

SOURCE: support engine and remove top motor mount for belt

The best way is to rent an engine hoist, you don't want to support the engine with a jack and a block of wood, you could crack what ever the jack is supported on, and if the engine moves, you will never get it lined up with the mount.

SOURCE: i have a 98 gmc 4x4 jimmy and the freeze plug

A 2 hour trip with a freeze plug leaking is almost a guarantee that you will be buying a new engine. Stop driving it until you can get the freeze plug fixed. It will only take an hour or so to change it if your friend has an skill at car repairs. Hope this helps.

How many freeze plugs are on a 2000 blazer 4.3 vortec


The freeze plugs are spaced out in a straight line along each side of the block. If you see others at the same height in front or behind where the motor mount is, then yes it probably is a freeze plug.

Put a jack under the engine with a block of wood between the oil pan and the jack head. Raise it slightly to remove the motor mount through bolt, then remove the mount from the engine block. Now you should be able to replace the plug. Use a punch to drive in one side, then grip with pliers and pull it out. Clean the recess before installing new plug. Auto stores stock them in all dimensions, or take your old one in for matching up. The rubber expansion plugs work well, too, and easier to install.

How do i change freeze plugs in a 1989 ford f150


To replace the freeze plugs you will need to locate the one to replace, sometimes you will have to remove things like an engine mount or bracket all depending on which plug you are replacing, using a pry bar and hammer hit the side of the plug this will make it spin and then pry it out, clean engine block hole with emrey cloth and then install new plug, its advised to use a freeze plug install tool to help avoid damage and proper install of the freeze plug, good luck,heres a picture of the install tool,

Freeze Plug Leak on my 1996 GMC Jimmy


i would hardly call this repair simple or inexpensive. the part itself yes the labor probably not. i have made this repair myself to my 97 jimmy if you have 4 wheel drive the transfer case up front makes this repair next to impossible from the underside of the car plus the fact that it is behind the motor mount means the the mount must be removed. this involves raising or removing the motor. simple? on a car of this age you will probably find (as i did) the motor mounts are damaged might as well replace them too the parts are fairly inexpensive. also look into replacing all the plugs so you dont have to do this again in a few years. oh yea use the proper antifreeze mix in your radiator water is what rusts out the plugs
