Default Check your rig, XJ suspension contacts oil pan + tranny lines

Over the years and numerous XJs, I have discovered another common issue.
When passenger side front suspension is fully compressed, the passenger upper control arm can make contact with lip of oil pan and with transmission lines, pinching or crushing them.

In my opinion, everyone should check the condition of pan and transmission lines. The location is the front passenger corner of oil pan. In this picture of my 1996, you can see where the oil pan lip has been impacted and pushed upwards. Luckily the transmission lines were unaffected. I have seen much worse on other XJs.

It can happen on the other side as well. My front shaft has eaten a hole in the exhaust and bashed the crap out of the o2 sensor.

Now that I think about it, my issue may come from the amount of time I spend on the bumpstops. Still the bumpstops should be longer from factory.

Even brand new bumpstops won't help when you need far stiffer shocks or another 3" of travel.

Jack the body up to decompress the spring
Shove the bump stop through the spring
Line the new bump stop up in the holder
Use a flathead or something else as a lever to force the new bump stop up and in the holder using the coil for leverage

No, I didn't drive to work today. Fortunately, I can work from home at my discretion.

I am seriously NOT in shape to be driving....


And now that a birthday bash for my daughter is done, off to bed!

I am enjoying this tread of elders. At 44, I'm not there yet, but do have Metamucil in the cabinet.

Stock bumps are called jounce bumpers. Come in two different diameters, there is a version that has a stud that threads into tower, and a version that is pressed in. Haven't figured out what years they correspond to.
The material is sponge like, rather than rubber.
