Hi this is my first post so bare with me Im just a chic I have a 1991 YJ 4.0l all stock except for tires ,31 x 10.5x15. Recently hydroplaned into fwy divider during heavy rain.The passenger front end took initial hit breaking the front leaf spring mount from frame and destroying leaf spring. Other side was a little twisted but intact. We replaced both springs with used yj rear springs. And a friend welded on a new shackle mount. The ride was fine at first the car felt solid and handled great. A month later the steering feels off and the car is a bit shaky. I am also hearing a deep grumbling exhaust like sound during acceleration and some clunking from the rear. Hoping for some suggestions on post collision inspection / troubleshooting. lack of funds and not wanting insurance to go up is forcing a DIY . Thanks for reading my post hopefully it makes some sense.


Ok here's pictures of passenger broken mount in front and area behind that tire. Ill take picture of same area tomorrow as well as some shot underneath engine compartment and view from front.

being it hit hard enough to break the spring mount(s), I'd check the front axle pinion yoke, front driveshaft, and the front output of the transfer case for damage as well... and while you're checking things, check rear output of Tcase, rear DS, and rear pinion.... also check motor mounts and trans mounts to see if anything broke or shifted there. could have tweaked the placement which would alter the rear DS angle

post some pics of any confirmed or suspected damage if/when you can also

Welcome to the forum. Here are some things you can check:

-Check your ujoints (Free). U joints going bad can cause a vibration.
-If they are good check and see if you can shake the yokes on the front or rear diff (free). Could be bad bearing.
-Lift the front tires off the ground and see if they have play in them (free). I have replaced a few hub assemlies.
-Pull the rear diff cover and see how the gears look (cost of gear oil and permatex).
-Check your ball joints for any free play (free).

These should be a good start.

I assume you aligned the front end. Do it again and see if it moved. If it did move, try to figure out why and also retighten everything.

Aligned as in by a shop
Not a shop but once everything was disconnected. The axel(? ) was lined up meaning measurement from center of tires to rear tires were a match. Will remeasure and take pics

Ok this is a late update regarding issues with my Yj after collision . First thank you for all advice. When I met with mechanic he was did not expect me to have such a high level of understanding of the mechanics of our jeep.
We ended up replacing the following:
tranny mount
both motor mounts
rear output seal of driveshaft (?)
valve cover gasket was redone and solved our constant oil leak issue. A different shop tried to tell me leak was caused by rear main seal and replacement would be $800
We also had Some other maintenance like reset tension on serpentine belt, fuel filter, radiator cap oil chage done and
Jeep is running much better now.

Thanks again for all of your advice. Enjoy your weekend
