Correct Nuts & Bolts?

Hey,

'88 XJ Cherokee Laredo 4.0L Auto 4WD.

I just received some Nuts & Bolts for the Upper Control Arms and wanted to know if they are the correct ones.

1. One of the Bolts is around 3-1/4" Long. The Head is Flat Round with a Torx in it. I have the matching nut for the threaded portion.

2. The other Bolt is longer, around 3-3/4" Long. The Head is Hex Nut with a weird looking "washer" attached. This "washer" is teardrop shaped with the bottom cutoff. You'll know what I mean if you're looking at it.

And I have the matching nut for the threaded portion.


Thx, Phil:smile:

Hey,

Can someone who knows the ans please reply.

Thx, Phil:confused:

Unless someone has removed their upper control arms recently they would have trouble answering your specific questions about the fasteners, hence the lack of response. Are your control arms off now? Do you have the original fasteners? Where did you get the new ones?

New hardware should always match the originals and be of equal grade.

Hey Stock,

Thx 4 the reply. I had most of the suspension changed with oem parts from Quadratec. The Mechs reused most of the old bolts since I didn't have any new ones (they said old ones are fine).

But they broke one of the UCA bolts and replaced it with one around a 1/16 of an inch smaller diameter hence my question. I've been driving around since Aug and even hit some pretty big potholes w/o any probs. Should I even bother changing the smaller dia one with the correct (if it is the correct one) size one?

I got the replacements from an auto recycler.

Thx, Phil

The bolts they used probably will be fine, especially if they were of equal (or better) grade as the originals. Personally I would want the correct bolts in there if it were mine. If the new ones you now have are larger and still fit, then they are probably the right ones. Plus check the amount of lines on the head of each bolt. More lines = higher grade. (stronger)

Graded bolts are a priority when installing certain parts.Most cars and trucks use Grade 5 and 8 ( 3 lines on head 120 degrees apart Hex head , and a grade 8 ( 5 lines) the higher the grade the harder the bolt. For instance your car seats are locked down with grade 8 bolts the reason your floor or mount should break or bend before the bolt breaks.-Chris
