Rear End Housing Spring Perch Welding
« on: February 20, 2020, 02:46:05 AM »
Looking to have a set of spring perches welded onto my 12 bolt. Is there anyone out there who has had this done and is happy with the quality of work? I live in the Massachusetts.
Thanks.

I had my father in-law weld the spring perches on my rear end and they came out perfect.

Try your local trailer hitch installer or a reputable muffler/exhaust shop. Any good welder with a MIG can do this simple job.

(Specialty) Rear End shops also should be dialed in on this, Like a Randy's Ring & Pinion service "IF" they are local to you?

Welding it is relatively simple for a pro but making it look factory is a different story. And, there are a lot of angles involved in their placement so do some research.

1.5-2 degrees is a 'general' measurement for most pinion angles on domestic rear wheel drive cars. That 'should' put you in the ballpark.

Pay a professional to weld it, many axle tubes have been ruined by excessive heat by inexperienced people. Also the repo perches need lots of grinding to make them work correctly. If you can borrow a known good housing you can make a jig on the bench and tac the perches on at the correct location and angle then have someone final weld them.

I'd be interested in what the jig looks like also.

Just use the google machine there are several examples. It's basically a solid shaft that goes through the axle tubes and the housing with bushings for the axle bearings and carrier bearing to make sure everything is straight and true when you start and the same when you finish welding on it.
