I loaned my set out and now my "buddy" can't find them. Can somebody tell me if my memory is correct? They are moog t411 and t412 sizes? My goodness they are expensive. I think I paid $30 for the set 20 years ago.
Can anybody recall the sizes I need for A body ball joints ?
There are 2 sizes for A-bodies.
The a-bods through model year 1972 use the smaller socket.
73-76 use the larger.
Personally I would not use an impact to install. There is a "suggestion" of a thread when inserted into the UCA but it is fragile, it is far from being a durable thread.
I remove them (or loosen them) and tighten them while the UCA is still on the car. The correct socket, a breaker bar, and my floor jack handle does it for me every time.
So is the 1 7/8 socket a 4 point or a 6 point??From: geregistreerd via Argeweb
The easiest way to remove your upper ball joints is with a special socket (see picture below). There are three different sizes, for A, B and C-bodies.
A-body - 1.809"
1960-72 A bodies
B-body - 1 7/8"
Strangly enough there are also 1 59/64" sockets, which should fit the same ball joint?! My ball joint is a Moog K772 and the 1 7/8" fits like a glove...
73 and up A-body
63-78 B-body
70-74 E-body
C-body - 2 1/8"
Strangly enough there are also 2 9/64" sockets, which should fit the same ball joint?!
Mopar used three different upper ball joints on their RWD Torsion bar equipped cars from 1957-89.
1960-72 A bodies only used the small ball joint
1957-75 Imperials and 1974-78 big cars used the biggest joint (MOOG K778) It was also on light duty Dodge vans from 1971-03, 1972-93 2WD pickups as well as 1987-96 2WD Dakotas and most Vipers.
Everybody else used the middle size (MOOG K772) i.e. 1973+ Darts/Valiants, F-M-J bodies, most C bodies till 1973 and all B-R bodies
Some sites where you can buy these sockets:
Mancini Racing
American Muscle
Summit Racing
Ebay Motors
JEGS
All balljooint sockets i've seen are impact sockets. And that's what you want. The easiest way to use these sockets is with an impact gun (electric or air).
You really want to do this with an impact gun. Because those upper balljoints are incredible hard to remove by hand, i.e. a socket attachted to a breaker bar is a guarantee to injury!
If you don't want to buy one, 'cause you know this is the only time you need one, maybe you can borrow one. I belief you can rent these sockets in the United States. Food for thought, I think...
My sockets are from SK Hand tools. Just type SK and the serialnumber in a search engine and the stores who sell them pop up.
1 7/8" - s/n 84688
2 1/8" - s/n 84689
I've read that SK Tools is out of business. So finding a new SK socket is probably rather difficult.
A PST socket (Performance Suspension Technology), This one is with a 1/2" drive.
They are specific for the shape of the ball joint. Not a square or hex socket.So is the 1 7/8 socket a 4 point or a 6 point??
