Question about 1994 Jeep Wrangler

1 Answer

I have a 1995 Jeep Wrangler. I needed a new muffler and a good tune up. The mechanic replaced the catalytic converter and muffler, including a tune up. The check engine light remained on (steady light) and fan belt continues to make noise. I informed the mechanic less than two days later. His reply was that he also replaced the oxygen censor and that would be the reason why. Less than 2 weeks later my Jeep began to lose battery power and hear very loud knocking coming from the engine. The engine/catalytic converter was bright red! Do I have the right to request replacement at no charge for less than average service? What do you think? Thanks, Mary

If work was performed either without permission from you, ie: o2 sensor? they cannot charge you for it. If work done is sub- standard, you have the right to a refund or correction to problem (at no charge) If any work done fails within 60 days, Same applies. (this is common to most state laws)
Noise and discharging sounds like a broken serpentine belt or bad alternator but I can't see/hear it from where I'm sitting. In my opinion, if the shop did not adress this problem, shame on them. But since they did no repairs related to this, they have no liability pertaining to that issue. Best thing to do is to have them resolve problems they caused, then find a more reliable shop to service your vehicle in the future!
Your state may have a complaint resolution department as part of DMV. It wouldn';t hurt to get them involved in this>
Good luck, RS

I just had the van in to midas muffler to repair the muffler system and the mechanic said that I didn,t need the catalytic converter muffler in front of the big muffler and did the repair eliminating the...


I would go back immediately to the mechanic and demand that the catalytic converter be replaced at their expense. The converter is needed for not only the vehicle to run properly, but also to pass state inspection. Some state laws insist that the vehicle have the catalytic converter. Midas should have known better, and I would definitely demand to speak to management or someone in corporate to have this remedied. I hope this helps and good luck.

Replace 1995 jeep wrangler catalytic converter


If it has flanges on both ends, just unbolt it and replace. If it has welded pipes you will need to cut it off and use adapter sleeves and clamps. Really not rocket science...at worst, you may need to remove the hangars on the rear portion of the system to get enough room to install.

Replace muffler, not the catalytic converter which started to rattle. Stop running, will crank but will not start. can it be the catalytic converter.


if the converter is rattlin then it needs to be replaced because the element inside is broken. if the jeep still does not run try removing the catalytic converter to see if the restriction is too much. should start if the converter is restricted. if it doesnt maybe its whatever caused the converter to go bad in the first place

Catalytic converter


HI, this guide will help you with this replacement.

Step1 Lift your jeep. Unfortunately, the catalytic convertermag-glass_10x10.gif sits about midway down the length of your jeep, so lifting one end or the other will not do. Ramps are your best bet to get you within reach of the parts when working from home. Luckily, this is usually the hardest part of this repair. Step2 Be patient with the bolts, as they are often hard to remove due to size and awkward placement. You may have to drill or saw bolts to remove them. With this in mind, you should pick up new bolts, nuts and seals for your replacement project. Step3 Buy a catalytic converter specific to your jeep to avoid extra work. A generic part must be welded into the jeep, while a vehicle-specific model comes pre-welded to the proper pipes for easy bolt-on installation. Step4 Remove the 02 sensor (with an O2 wrench) before unbolting the catalytic converter. Then, you should remove the pipe connecting the sensor to the converter. Depending on your exhaust system, you may have to remove more pipes before you unbolt the converter from the muffler. Step5 Replace the old catalytic converter with a new one. This should be the easy part, as you simply bolt the new part in place. Step6 Reattach the exhaust pipesmag-glass_10x10.gif and 02 sensor, and the basic job is done. Make sure you replace any cracked or rusty pipes while you have the exhaust system apart.

  • Catalytic converters often fall under a separate emissions warranty that lasts at least 7 years and 160,000 miles. Even if your car is out of its regular warranty, but it is a newer model, ask your dealer to replace the part for you free of charge.
  • Rent the O2 wrench or socket if you do not own one. Most auto parts stores carry this tool for rentals.
  • In many states, older (vintage) cars do not need a catalytic converter, so you can gut it or remove it completely. No damage will result from running a car without a converter.
  • Due to emissions standards, it is illegal to buy or install used converters.
Please rate and god bless:)

Replacement of catalytic converter 98 Wrangler


you don't have to remove any hangors, but some times its easier. After getting it all off, it goes back on the same way. I prefer welding the pipes shut, but its not neccessary, just make sure the U Clamps you are using are good ones and tightened good.
