LCA bracket

Hi guys. Could you please tell me if it's normal for the driver side lower control arm bracket attached to the axle to look like crooked into the inner side? Maybe if you could share with me a picture of yours, will appreciate it. I just replaced both lcas and bushings and noticed it. Below there's a picture of it. I'm trying to fix a vibration coming from the front side like on the dash and steering wheel strating at 40mph and I'm a little lost. Just did alignment and wheel balance and got my u joints inspected, they look in good condition with no play. I still have to get the damper/stabilizer/steering strut replaced.

If memory serves it does look correct. What transfer case do you have? I had a front end vibration that ended up being the centering ball in the front shaft double cardan.

Nope, not normal. Someone has hit a kurb or driven into a ditch with that thing.

I have the 242 AFAIK. You mean the point where it appears to have 2 u-joints coming from the TC to the front?

Even if the arm looks straight into its place? Doesn't look crooked or at an angle, compared to the one on the passenger side looks the same. I'm really confused, if anyone could take a picture of yours would be awesome

Bracket and LCA should be at a right angle to the axle tube when looking from the front. In your pictures it looks like the bracket/ LCA do not sit correctly. Might be a camera angle thing though.. Can be easily verified with a right angle tool.

I'll have them inspected then. Because it indeed looks out of angle like pushed to the center

The centering ball in mine went bad and was causing a vibration. With the 242 you can pull the front shaft and test drive it. That will confirm or eliminate drive shaft play

Now that I looked at a few old pictures of my XJs and the ZJ with OEM LCA brackets, I am 100% sure your bracket is bent. I was 99.99% sure before that If you had a welder it wouldn't be a big deal to replace the front LCA brackets - not having one I highly suggest hitting the local junkyards. It is not a good idea to drive around with bent control arm brackets.


Most 4.0s had 3.55 gears, V8 3.73; '96+ used short lo pinion, earlier were long lo pinion. Also check the pinion if it has yoke or CV flange, get the correct one for your front DS style.

You 2 guys are great. Thanks for the advice. I will do that test drive without the DS to isolate the issue and hopefully find a solution, and the do the bracket.
I don't have a welder so replacing the thing from a jy means bring all the front axle home?

I've figured out the vibration issue, the front cardan / drive shaft spins outta its place like up and down. Any advice on where to buy that piece?

Spicer 211544x - non greasable
Spicer 211355x - greasable

The non greasable is easier if you dont want to mess with the hassle of grease points.

The non-greasable one requires the separate rubber boot that tends to wear out, which is an added cost. The greasable unit actually seems to be a bit better sealed than the non-greasable, FWIW.

So, you're saying to just replace the u.joints or is that for a new DS?

We're saying to replace the U-joints and centering ball assembly, the part numbers provided above were for the centering ball. To do a complete front shaft rebuild you will need 3 external-clip 1310 U-joints and a centering ball. It's a pretty straightforward task if you have a balljoint press handy.
