HOW DO I ADJUST THE DOOR HEIGHT FROM STRIKING THE LATCH TOO HARD?

on that old of a car, you should be able to just loosen the bolts that attach the door to the hinges. however if the hinges are worn out, then you are fighting a loosing battle. need new hinges, or at least new pins before you can properly adjust them. you may also have to adjust the position of the latching post at the rear of the door, so it will strike the post properly.

It could be either the latch has jumped off the Cam inside the latch mechanism or the spring inside has jumped off back a bit onto the same Cam, I had the same problem with mine. If it's the simple ball bearing type it may just be dirt and so a wee squirt of WD40 may do the trick.

To fix the door knob lock, close the door slow & watch how the latch bolt meets the strike plate.The bolt may be positioned above, below, or 1 side of the strike plate.Its also possible the door has shrunk & the latch no longer reaches the plate.-------------------------------------------------------------------------------------------------

is the door latch mechanism moving and moving far enough to release the latch to open the door,you can`t remove the the striker plate from inside a panel as the bolts that hold the plate go in from the open side of the door jam,these do have a problem with the doors coming off the rails which mean that if this is the problem then the weight of the door will hinder the door from opening you may have to hit the door hard at the latch end of the door or even pry the door open at the same end to get the latch to pop open.the latch may even be seized or just jammed closed. good luck

usually the door latch will go bad when the door hinge bushings are very worn. Inspect the door hinge by holding the door a grab the outside door handle and the door shell firmly. Now lift the door up vertically and see if there is any play in the hinges. If the slightest movement is found replace the door hinge pins and bushings. your door latch may work great again If not replace that too

The latch may have gotten tripped without being latched. Look in the latch area of the door and see if you can stick a screwdriver or a pen into the latch from the end and pull it towards the inside of the door while pulling on the handle. The screwdriver should pop free and the door may work then. If it does it regularly or won't latch still, you may need to adjust the strike (the bolt-like thing that sticks out from the door jamb) Loosen it with a T-47 torx bit and tap it up or down until it line up with the latch. adjust it in and out until the door latches reliably and is lined up with the body when latched.

Yes but the bonnet was latched by it's strike to the latch attached to your cars radiator support therefore pulling the radiator support out of alignment and the hood/bonnet and strike are in the proper position. The solution is to adjust the bent radiator support to it's latch is in alignment with the strike.
Good luck

Adjust it for what? I am gonna say that it is probably not striking the stiker latch dead center and is below it and when you close it it hits and you either have to hold up on the door or it hits low and then closes hard. Solution: the striker pin at he opposite side than the hinges is the rod that sticks out where the latch hits. It can be unloosened by a wrench or star wrench or allen wrench head depending on vehicle. Lossen it move it which way up or down till it latches good. this is a cure for bigger problem usually the hinges are worn and the door is dropping down (especially on long heavy car doors, usually 2 door versions) Check the hinges by lifting the door up at the entrance end if it lifts and drops sloppily on the hinge or moves on it without the entire care moving up and down it is worn. If you are actually adjusting the hinges. Try putting a long wobble head extention on a rachet or whatever allows access to the hinge bolts and put them in place and then close slowly and adjust till all body lines line up and door closes good without interference.( this can be a little tedious) use 2 people or 3 it really helps. If all this fails take it to a body shop and for a small fee they will do it in a few minutes.

Remember that there is a little play in the hinges, even new ones, enough that just a slight degree of play at the hinge axis will result in several fractions of an inch movement at the latching end of the door. The key here (assuming the lower hinge is still mounted at factory height with respect to latch) is to adjust the angle of the hinge's axis such that the latching mechanism is 1/2 inch higher than the stiker plate BEFORE tightening down the hinge's mounting bolts, then when you remove your support holding up the latch end of the door it should sag back down approx 1/2 inch and line up perfectly with the latch plate. I used to do this on an old '79 Monte Carlo I used to have and even being the smallest of the Monte's, it still had fairly long, heavy doors for back then even and could get the doors to shut/latch perfectly. I own a VUE now-a-days and its door's are featherweights by comparison so they should be fairly easy to adjust and you shouldn't have to tighten the @#$% out of the mounting bolts during the adjustment, just make sure you tighten them good when the alignment turns out correct upon final inspection.
If your adjustment sags again after shutting the door a few times, then you didn't tighten down the hinge mounting bolts enough and will have to go through the adjust procedure again making sure to tighten things up better the 2nd time around.

electrical tape the strikepins then loosen the strikepins with a pipe wrench and, readjust tighten and, remove the tape.
Sometimes the strike pins have a plastic sleeve if this is missing you must replace the strikepins because their diameter will be too small for the latch jaws and will rattle.
