replacement needed

[southdave]

To make a long story short, I manage to shear the rivet off(all three) the drivers side leaf spring shackel, where it attaches to the frame. So I need a replacement bolt size and grade. At first i thought, grade 8 but rivets are made of malible steel ect..

Go to the hardware store and get a bolt that fits. I would use grade 8 but I'm sure 5 would work just fine.

 

[southdave]

if use 8 grade will that cause other damage. I know just run down to tractor supply get three set of bolts & nuts get somthing that close, but I want somthing that I will not worry about when I'm doing 50mph and hit a chuck hole.

 

[Westech]

well then use grade 5. Your not going to brake grade 5 unless you smash it up good and even if you replaced it with "factory" rivets and hit the same thing its going to bust. Just put 5 in it and be done.

The hole is a little odd size. Too big for 3/8 but too small for 7/16. I drilled mine out for 7/16.

i used grade 8 when i bobbed my truck. i have not had any problems and i don't think you will either.

Over engineering never hurt, Use the stronger bolts

 

[gimpyrobb]

Sounds like you need new bolts(7/16) and a smarter driver!

 

[southdave]

softer bolts and drilled out to 7/16 I think is the answer cause I can't be fixed thanks

When I used to stretch and shorten frames we used hardened washers, grade 8 bolts and lock nuts.

Grade 5 bolts will work, however a grade 8 bolt will give you a higher load allowance. Rivets were used because they fill the holes when compressed while bolts require a tight tolerance hole.

If you are going to open the holes up to allow for a 7/16" fastener, make sure that you

1. FIRMLY clamp all parts together.
2. If you use a drill bit, use a quality cobalt drill bit with oil.
3. If available, use a reamer to open the holes up.

The last thing you need is a hole that the fastener does not fit tight into. Any movement in the fasteners will allow for the fasteners to either start egging the holes out of the fastener will start to be eaten by the shearing action of the suspension movement.

Currect me if im wrong but dont the hangers have a L or U shape and if thats the case then you wont have to worry about bolt strength because the hanger will take the load the bolts will just hold the hanger on there

this is kinda my way of thinking too... (I would still use gr.8 thought)

 

[dobyg75]

Agreed

 

[docfarmall]

the shear factor of grade 8 bolts is higher so they will fail before the grade 5 bolts drill out to 7/16 and use grade 5 my .02 cents

Same here, far down south....
