Putting together my spindles after paint and powder coat. Should I loc-tite all the bolts? Anyone know what the torque specs are also?

I asked this same question and was told no not a good idea. As far as torque specs go I have them written down somewhere if someone does'nt chime in I will get them for you.

This is from one of our moderators - David Pozzi. Check out his web site and you'll find tons of good info: http://www.pozziracing.com/first_gen_suspension.htm

All are in foot pounds-ft
Steering gear mounting bolts-70 ft
Pitman Shaft Nut 140 ft
Steering Wheel nut 35 ft
" with tilt 1 ft
Steer coupling nut 18 ft
Steering coup clamp bolts 30 ft
Tie Rod End nut 35 ft
Tie Rod Clamp nut 130 ft (correction, 130 INCH lbs)
Ball joint nut upper 50 ft

Any idea why? I can't think of a bad reason to use a medium strength type locker.

I don't understand why either? I put my spindles together tonight with the correct TQ spects and a dab of loc-tight anyway. I'm not going to put it on the ball joints and stuff like that though.

Because the whole idea of torquing to spec provides enough clamping force to stretch the fasteners and create enough friction in the threads and bearing surface of the bolt head or nut to stop them loosening.

Sure, you can Loctite them, but why?
Millions of cars on the road and no Loctite anywhere.
Any fastener safety measures are taken care of at the factory with locking washers or crimped locking nuts.

Also, regular Loctite might be useless with the heat of the brakes tranfering through them.

Tie rod clamp bolts 130 ???

Is that a typo?
s/b 30 IK think.

Suspension parts are either press fit (ball joints and bushings), use locking nuts, and/or cotter pins, so Loc-Tite isnt necessary.

correct that should be in-lbs, David's site has the correct number http://www.pozziracing.com/first_gen_suspension.htm#Bolt%20torque%20specs

On dirtbikes, we loctite nearly everything. I would not think that a spot of 'blue' loctite on any suspension bolt is a bad thing. Bolts that size would normally take 'red'. I will be replacing my entire suspension with the next couple of months and will probably use a drop of blue on every bolt.

I don't see a problem with using locktite but it probably isn't going to help anything since GM screwed together millions of cars without it and there hasn't been any problems.

It could cause problems removing balljoint nuts, the stud would just spin around.

To convert inch lbs to ft lbs, divide by 12, so 130 inch lbs is 10.8 ft lbs.
