Hi all,

 

On my 97 MPI, the door hinge studs have seen better days and the nuts are just spinning. Can the studs be changed ? if so, is it easy to do ?

 

Thanks

 

Pete.

drill them out and weld new ones in.

 

or buy new hinges.

Good advice Nick, you need to take the door off, then pull the hinges off the door - new hinges are expensive (I think, but I'm a tight git) so swapping new studs on your existing ones is worth doing if the hinge itself is good.

 

I'd allow yourself a day if you are a leisurely worker ... it's 4 bolts to pull the door off, 5 screws to remove the hinges from the door ...however these can become stuck / rusted with age (soak them with a penetrating oil before you start for a few days) - I use a 18V drill with the correct screwdriver bit in it, an impact driver would do the same thing.  Then it's remove the old studs, weld the new ones in and spend sometime rehanging the door again.

Its a pain to get them set correctly and welded in properly.

 

Now you can pick up second hand OE hinges but you may find the hinge pin is worn.

 

There are two types of new hinges out there, pattern and Genuine. Now personally after being bitten by pattern i would always buy genuine.

grind the weld off and the hinge is threaded, screw new stud in and a tack weld job done

The hinges are off the car. There is no play in the pins so I would like to keep them, new OE ones are nearly £200 for a set of 4 !!!!!!

 

I will have a play with one and see how it goes.

Replaced all the studs on my hinges with 8mm A2 grade 304 stainless steel studs. Drill out the old studs. A good tip is to grind off the back of the weld flush as it is very hard to drill. Go through with a 1/8"drill and punch out what is left of the stud and drill to size. I TIG welded the new studs in with stainless weld. No more rust!

That's exactly how mine are getting done, nice!

grrrr why drill them the hinge is threaded as i have said cut the weld off unscrew broken worn stud out, then fit new stud and put a nice weld on job done no drilling :)

[Itsjustanestate]

The weld had penetrated too deep on mine so I just snapped the studs. Much easier to grind off flat, center pop and drill. Also stainless studs will out last us all!

Wish I'd read this last week, did a search for threads on hinges and missed this one   Pins all worn out in mine, so ordered a pattern set of hinges. Awful. Miles out when trying to line up. Genuine it is then! *sells another limb*

What was falling for us but mainly my son is he spent a lot of money on DSN billet ally hinges so after all of the gapping, welding etc I did on his doors it was all to no avail.

The lads at DSN even offered to modify the hinges to fit but as all that work had gone into gapping the door exactly with pattern hinges we politely declined. They did do a double check of the thickness of their own hinges anyway to make sure all was good and confirmed they were dimensionally correct to OE hinges.

A hard lesson learnt.

Ah heck, sounds like a frustrating time! The guy doing my resto has repaired the doors and wants to get them hung and gapped before starting to put the new front end on - from the A Panel forward - so we're just a bit held up waiting to get some decent hinges sorted. I'm trying to stay zen about it all :) Cheers for the info!
