Lower Ball Joint Replace DIY (almost)

Replaced Lower Ball Joint

I looked forever all over here and the Internet and could not find how to replace my LBJ for my 1990 300SE. It seems other models were way different and needed to have the spring compressed, lower control arm supported, or strut removed. I didn't need to do any of that!

Jack up car and support on stands (need new tires)

Remove tire, brake caliper, rotor

Remove tie rod from steering knuckle (2 19mm bolts)

Remove shroud and sensor

Remove bolt from upper control arm to steering knuckle

Using a tie rod tool, detach steering knuckle from upper control arm

Pull steering knuckle away from car to access ball joint bolt (22mm)

Loosen ball joint bolt

Using ball joint separator (HAMMER), break ball joint free from lower control arm
Steering knuckle should fall off with ball joint still in place

I took the steering knuckle to Sears and they removed old ball joint and pressed in new one for $45.

Before going to Sears, I rented the ball joint tool from Pepboys but it would not work because of the size and space inside the steering knuckle.

Install in reverse order

*Use floor jack to lift and guide steering knuckle into upper control arm

Don't forget to re-grease wheel bearings

MB wanted over $300 to replace one lower ball joint and my Indie wanted $200.

Ball joints 2 ea. $44
Tie rod tool $10
Ball joint tool $10
Sears $90

$154 total. Some places may be cheaper than Sears, but I was happy they could do it right then. I was in and out in 20 minutes. I took the second one back to Sears and was in and out as before.

Thats fantastic, i recently replaced the lower ball joints along with the upper control arms. Didn't take to long, hardest part for me was waiting for that tight front end. Then realized i really need guide rod joint replacement.

+1 on the above.

Girding my loins for this (and the rest of the front end) - parts are starting to pile up.

Attaboy tgordy41.

Just say no to sparkplugs[SIGPIC]

Thanks for photos and info,

I have 85 380SE. Are there upper ball joints as well as lower ball joints? If you know. Thanks. RT

RNT,

The upper control arm has bushings and a ball joint that will go bad over time and need to be replaced. I replaced the whole upper control arm since the new one came with the joint and bushings. On the lower control arms, you will want to check for play in the tie rod ends and center drag link. It's cheaper to order the complete tie rod (with ends) from Autohausaz.com.

Thanks for the write-up. I just received my new LBJ just the other day. Planning to get on to it this next week.

Hi All,

Hi I am a new member today and think this is a cool site. I just got a 500 Sec 1983 and I am doing this job right now. Thanks for the info tgordy41. I am having trouble getting the sensor out. I have undone the small bolt and the sensor moves from right to left when I tap it but it will not move out of its hole! Also what way does the ball joint come out upwards or downwards through the arm? Or is it just imposible to DIY? Thanks for any replies I am getting frustrated with the sensor and if I ever get it out I will find someone to get the ball joint out for me.
