Couple of Q regarding replacement parts

Q1
I had a "clunk" from front end and saw the swaybar-to-frame bushings were shot, so I had them replaced. But the "clunk" is still there, in some (not all but most) of the turns, when the body leans. It feels like something hits under my feet. So I guess I'd have my front control arms bushings replaced. Can somebody tell me how many bushings are there in the front (both upper and lower control arms), since I really can't figure it out. I looked at rockauto.com and some are sold as one, some as a pair, there's "front" label but also "front lower rear" all together, so I can't decide what to order.

Q2
A/C was recharged, with the color so it would point to a leak, and it discharged pretty fast (month or so - without even using it once). But there are no traces of color anywhere, so the mechanic guy concluded it's a part that is inside, on passenger side, and it requires the dash to come out to be replaced. He gave me the name in my language, but I don't know how to translate it so I could order it. He said it looks like a "radiator" in the front of the Jeep, approx the size of a thick book (encyclopedia or similar). Like a radiator, with all the little "ribs". What's it called in english?

If it's easier, I'm ordering all from rockauto.com so if somebody can point me to the right part number+quantity (for control arms bushings) and maybe partnumber or name for this "radiator" for A/C, I'd be very grateful!

Thanx!!

I'm sure someone will correct me if I've got this wrong but:

The condenser coil is in the front of the radiator, the evaporator coil (where the cool air comes from) is under the dash.

I'd also be looking at new hoses if you're going to tear into the A/C that far. You might want to have your mech. just pull the dash and check the connections to the evaporator coil. Doesn't seem too likely that the evap. coil is bad/leaking.

Good Luck!

I just had a "clunk" on my 97 zj, it was worse during the turns. I took it to a shop(forgive me), it was the u-joints in(at) the wheel hubs. Makes sense when you think about it, so I'd have them checked before you replace the control arm bushings.(just my $.02) My sway bar bushing are also shot, I'll do those myself.

Yes - first you should check U-joints on wheels. Had same problem with "clunks" about 6 month ago on my 93' ZJ. Just turn the front drive shaft in different directions with hand & see some play in U-joint.
Replacing U-joint can be done at home - not so difficult, except regular tools you need 32mm (if I am not mistaken) deep socket.

The AC recharge with a "color" usually shows up under a black light. You either need a really strong black light or just wait until night and use any black light.

Any thread detailing on this? From what I found via search, it seems like a serious job, requiring pulling of the axle from the shaft and other complicated stuff

As for evaporator core (I belive that's the proper term), I'll be ordering one. It's a big job taking the whole dash apart, discharging the coolant from the engine, removing the PCM, coolant reserve bottle to get the A/C-Heater unit out, then removing the evap. core from it - to be done twice. I'd rather have a spare evap.core standing by (and it comes with tubes attached) in case it needs replacing it can be done right away. PLS correct me if I'm wrong...

Not very complicated. I did it on passenger's side & changed driver's hub for about 3 hours.
Pulling out the axle - you should pull it only a little bit for comfortable work. It is rather difficult to turn off the hub nut by your self. If I remember the proper way, in manual it is said that you need to unscrew the hub nut through the wheel hole, but socket doesn't fit this way. So take off wheel, brake caliper (unscrew 2 bolts on the back with 1/2" socket, push brake piston in, don't forget to tie the caliper to spring) & rotor, then unscrew the hub nut - push any metal rod between axle yoke & axle case (don't really know how it is called in English) for stopping the shaft. Then take off wheel hub & pull the shaft a little bit - you are free to go with U-joint. Install in reverse, apply a lot of grease in new joints. When doing this you can also grease suspension & steering components.

Ahem. Seems too much for a parking lot, which is the only place I can work at :/
I guess my mechanic will be seeing me soon...

Of course it is better to perform repair in professional shop. But you can still try DIY.

I can understand where you're coming from about this. Esp. since the parts are tough for you to get.

Good Luck, Stay Cool!
