Hey all, so I have an 87 4runner and just finished putting a 4.56 diff in the front. Only problem is that the nuts from the diff/CV contact the LC arm alignment bolts.....what the hell! Drivers side cv, perfect, passenger side...at best I can get 1-2mm clearance only. I don't see(with a straight edge) anything bent either. Crappy Trailmaster 4" lift in it. Thanks for any info

 

Can ya get some pics of what you're talking about?

 

not right now no. If you were looking down on the front diff from above the vehicle...passenger side where the cv bolts to the diff. The nuts on those studs hit the alignment bolt on the lower control arm.

 

Side shafts aren't fully seated or the rear mounting bolts bound up to early, just guessing can't see it

 

what do you mean by not fully seated? Damn picture nazis

 

The best description in the world will still render any responses just a guess without any type of visual conformation. I know the world wide web thing is great, but there are limitations with just descriptions. Hate to say it, but your description is vague at best, which will render any and all responses...just guesses. I hope this dynamic I describe is not news to you.

Honestly, what you describe it could anything in the front end being off. Besides, what is a LC engineering arm? See what I mean about being vague.

Pictures or I hope you can figure it out yourself...

 

reading failed "LC arm" not "LC engineering arm". Anyways...

Did you drop the crossmember? Did the bolts slide right in or have to be forced if you did drop the frame crossmember? If the frame is slightly tweaked the bolts won't slide in easy, this would eat up some of your space.

Sloppy bushing at the front, more space lost. Rear mount bushings, pre binding or hard, more space lost.

After looking at some other pictures, #1 #2, my new guess is your control arm adjustment bols and nuts got direction swapped (nuts go to the outside), and maybe you still need to tighten the mounts up more.

It shouldn't sit low enough to interfere, and the bolt heads shouldn't stick out far enough to contact should hit the control arm lip before the bolt head.

 

Yo, I used to like sitting at home internet wheeling to

 

yes, dropped the rear crossmember so the diff would drop right out. never removed the alignment bolts though, didn't want to throw off the alignment. The nut on the wrong side got me excited, but they are on the correct side. Trying to borrow a digital camera so I can post up a picture.

 

that happens to me after i add spacers to lower the front differential.i just loose differential mounts, with a pry bar push the diff back to increase the clearance and tight the bolts again.
