I'm installing subject on a TCI frame and have a question for anyone who has installed R&P. I have the bushing flange between the rack and the frame, followed by a washer and nut on the frame. The bolt enters the rack from the front with a washer between the bolt head and the bushing.

Note that the tail of the bushing extends forward past the rack about 3/4 inch before touching the bolt head. I presume the flange between the frame and the rack is to eliminate squeaks and absorb shock. The rubber protruding rubber however causes me to question, just how tight should I torque it down? I've posted pics in my journal. Note that I'm not even sure there is supposed to be a washer in front of the bolt head. Can someone verify this? The bolt I understand to be a grade 5....but I don't know what this means in terms of torque. I've got a feeling I can't over tighten by hand, but I don't want to if there is something called too much.

Mfg, unable or unwilling to provide torque specs.

The nuts by the way have the neoprene inserts.

Use the standard torque for that bolt size, the rubber bushing has the metal sleeve inside, it will tighten down and mushroom the rubber so the rack is isolated by the rubber to absorb shock loads, note that the steel sleeve has teeth, be sure there is not too much paint on the chassis. you want the teeth to bite into the metal. hope this helps...

OK....So, the bolt is supposed to be a grade 5. It's chromed and smooth surface, so the grade is not verifiable....I'll have to trust the supplier on this one....It's 5/8 inch so, that should put the torque at 150-170.

What about washers? Does it get one between the bolt head and the rubber extension that mushrooms? According to the TCI, the flange goes between the frame and the rack, so the mushrooming portion will be on the other side of the rack. I suppose the flange will provide some shock absorbing qualities, but not near as much as if the mushrooming portion was between the rack and the frame. What can you tell me about this point?

Have you seen any manufacturer instructions on the internet by chance?

Buy some washers to go on the outside of the rubber bushing. I don't know why TCI can't provide 2 lousy washers. I have installed several of those and never seen a washer .

Also, the nylock nut that they give you to bolt the rack on WILL BACK OUT! use locktite and or drill the bolt and put a cotter pin in it. I do that to all of the ones I do. The stock nuts were deformed thread type, they have alot more resistance to loosening.

I'll look up the torque spec for the bolts. I don't remember them being 170ftlbs. That seems a little high.
My book is at the shop. I'll put them up tomorrow.

later, mikey

Rack & Pinion

Thanks Mike:
I had actually already bought washers, but was a little reluctant to use them....I'm thinking I have a picture of a TCI frame taken in Louisville that shows the bolt head recessed into the bushing so that it sets against the metal bushing insert.....I'm going to post the picture to get your thoughts....I'm just glad I have found someone that knows exactly what I'm referring to...Thanks

I also read that locktite should not be used on plastic, but for sure I'm going to take your advise on the cotter pin....and maybe a little locktite won't hurt....

The torque spec, per a chiltons manual, is 100 ftlbs on those 5/8 bolts. I checked a couple of other places I had access to and found nothing else regarding torque.

Check ALL of the bolts and fasteners on that front end several times after you start driving that car

Later, mikey

I'm glad to hear I'm not the only one running into problems with TCI Kits. I dont know if I'd use them in the future...I'v had major problems with both front and rear suspensions...
good luck Joeford. Keep us posted on your install

one thing for sure, don't use a large washer on the outisde the rack can pull right off the car!
That makes no sense to me. Why would a large washer make the rack pull right off the car. Or are you talking about a washer with an inside diameter that would allow the nut to pass through it?

R&P Install

Thanks Mike or this dummy may have taken six shooter seriously. Of course it would pull through, at least until it hit the frame....I guess that settles that, the washer stays....Thanks guys...

ps...Yes, I'm thinking I'll stop every two blocks and check out the nuts....(ok...seriously maybe the first ten, 50, 100, 500, and 1,000)

My wife says she will follow me to Louisville....
